Despite Ross County's current standing in Scottish football, not too many would back them to pull off a shock and emerge victorious in Sunday's Scottish League Cup semi-final against Celtic.

Jim McIntyre's side currently occupy a lofty fourth place in the Premiership and also maintain an interest in the country's other main domestic cup tournament.
But can they make the next step and reach the League Cup final for the first time in their history?
There's belief within Dingwall that they can and some within the club have experience of pulling off the unlikely.
Take defender Scott Boyd, the club's record appearance holder. 2010 marked one of his career highlights, alongside team-mate Michael Gardyne, when the Highland club upset Celtic 2-0 in the Scottish Cup semi-finals at Hampden Park.
The scoreline prompted former BBC commentator David Begg to describe it as "the most incredible result in the 125 years of Scottish Cup history".
It was a thoroughly deserved victory for a County side still then in Scotland's second tier, against a Celtic team including the likes of Robbie Keane, Scott Brown and Aiden McGeady.
"As a club, we've been there before and we've managed to upset Celtic before," Boyd told BBC Scotland.
"We know it'll be a tough match. There's a belief in the squad similar to 2010 - one that we can go and compete at the highest level.
"Whether everybody else gives us a chance, that's another matter, but we definitely believe we can go there and get a result.
"There are a lot of good things happening at Ross County just now and hopefully it can continue."
Captain Andrew Davies also has previous.
He was part of last season's Bradford City side that came from two goals down to stun Jose Mourinho's Chelsea 4-2 at Stamford Bridge in one of the FA Cup's biggest-ever upsets.
"That game was just unbelievable," he said. "I don't think anyone expected us to go there and get a result.
"A lot of the lads have been in games when you go in as the underdogs and you think 'I've got nothing to lose'.
"In these occasions, you've got to try and find a balance between the pressure and enjoying it and, if you can get it right, anything can happen.
"You've got to take inspiration from those experiences and take it into this weekend."
If further inspiration was required, County goalkeeping coach Scott Thomson was the man who saved Paul McStay's shoot-out penalty as Raith Rovers shocked Celtic to win the League Cup in 1994.
Shocks don't come much bigger in Scottish football history, and add to the evidence that the unlikely can happen.
But manager Jim McIntyre knows that in Celtic, County face a side finding their form as they pursue a domestic treble.
Ronny Deila's side lead the Premiership by six points and, like County, are in the fifth round of the Scottish Cup.
And they have scored 19 goals in five games in all competitions so far in January.
"You've got to believe going into any game you have a chance of winning it," said County boss McIntyre.
"We know we're facing a team playing with real confidence. We're going to have to bring a level of performance that's right up there.
"I know we're capable on our day of beating any team."
What is different from the last semi-final meeting between these sides is that County are a stronger proposition. Celtic arguably are too.
But, as history highlights, in cup football anything is possible.


Electronics giant ZTE wants the public to help design one of its next mobile phones.

The company has launched a website where people can submit their ideas and vote on those of others.
Initial proposals have included a solar-panel case, a second screen that can rotate 360 degrees, and a modular design to connect with keyboards and games controllers.
ZTE has promised to release the "crowd-sourced" phone in 2017.
Known as Project CSX, the initiative was first announced in January at the Consumer Electronics Show in Las Vegas.
Submissions officially opened on 3 August, and ZTE's community website now features a growing list of ideas proposed by the public.
One user believes the phone should include a "desktop mode" that turns it into a rudimentary PC, while another says ZTE should build a phone dedicated entirely to Pokemon Go.
But the smartphone manufacturer has laid some ground rules to curb impractical ideas.
"Of course, there are always rules and restrictions to any competition.  The most important thing is that the product that we end up building follows ZTE's mission," said Jeff Yee, vice-president of technology planning at ZTE.
"It must be a mobile product, technically possible by 2017 and be affordable to the general public."
The initiative was a "bold approach for the industry that demonstrates how ZTE keeps consumers at the heart of everything", said Lixin Cheng, chief executive of ZTE USA.
But one smartphone expert believes the crowd-sourcing project comes with caveats.
"I'm sceptical that Project CSX will create something the world has never seen before," said Nick Wood, assistant editor of Total Telecom.
"One reason being, the final device has to be affordable, which probably rules out expensive upcoming features that require new manufacturing techniques like flexible screens."
Mr Wood said there was a pronounced homogeneity to smartphone designs, with many of the most popular phones adopting the same slate shape with similar camera and storage specs.
"Genuine, eye-catching innovation in smartphone hardware is the exception rather than the rule," he said.
ZTE is China's second-largest telecommunications company, after Huawei.
Based in Shenzhen, the corporation is known for its smartphones, but it also makes semiconductors and other products.


A group of orcas stunned whale watchers after surfacing just inches from the shore.

The killer whales were captured on mobile phone footage off the Shetland coast.
Diver and photographer Richard Shucksmith filmed the pod as they entered a small gully three miles north of Lerwick.
"It's the best orca sighting I've ever experienced," said Mr Shucksmith. "A big bull killer whale a metre away."
"I can only imagine they were hunting seals or fish, trying to flush something out.
"They came right in to the shoreline. They stopped in the gully for half an hour."
Mr Shucksmith operates nature photography tours in Shetland, but it was pure chance that the orcas surfaced at his location.
He had been diving on a separate photography project when the whales appeared on Monday afternoon.
"I grabbed my camera, but I only had my big lenses. They were so close I needed a wide angle lens, but that was in the car.
"My mobile phone was the only way I could film them."
Mr Shucksmith watched the orcas with a local family. He estimates there were about seven whales in the group.
The community runs a 'Shetland Orca Sighting' group on WhatsApp to share sightings around the islands.


Warrington Wolves prop forward Ryan Bailey says he would not have joined the club if he had not received help for depression.

Bailey, 31, was treated last year at the Sporting Chance clinic, set up by former Arsenal footballer Tony Adams.
"You think it's weakness but that's the best thing I've ever done, asking for help," he told BBC Radio Merseyside.
"I never asked for help in my life for anything because it's like weakness especially in a manly sport like this."
The former Great Britain and England international had short spells with Hull KR and Castleford last season before agreeing a one-year deal with Warrington in November.
"I used Sporting Chance because I'd hit rock bottom and I got really bad depression. It was the toughest thing I've ever done but the most rewarding. I got a lot out of it and I wouldn't be here at Warrington if it wasn't for that," he said.
"Leaving Leeds, my hometown club and a lot of good teammates there, and having to just get my head round that, I think I rushed into things with going to Hull KR."
The prop forward still feels he can play for a few more years despite his age, but admitted he faced competition to break into the Warrington side.
"I'm getting older now but I've got four five years left in me feel fit and strong," he added. We've got a strong side so everyone's fighting for their spot this year."


Hackers are "continuously" targeting medical devices and hospitals, the US Federal Drug Administration has warned.

The alert comes in new FDA rules that define how medical equipment makers should tackle cyber-threats.
Manufacturers should be constantly vigilant, said the watchdog, and make sure they can patch the flaws found in gadgets.
Its rules come at the end of a year that saw flaws found in many medical devices, and hospitals hit by malware.
"Cyber-security threats are real, ever-present, and continuously changing," wrote Dr Suzanne Schwartz, FDA associate director at its centre for devices and radiological health, in a blog.
"Hospital networks experience constant attempts of intrusion and attack, which can pose a threat to patient safety."
To tackle threats to devices in hospitals or worn by patients manufacturers needed to think about security throughout a product's entire lifecycle, wrote Dr Schwartz.
In addition, she said, they needed to:
Manufacturers should also become more comfortable working with security researchers who scrutinise gadgets for flaws, she said. Some researchers were threatened with legal action after highlighting a flaw.
Researchers have uncovered problems in many products, including defibrillators and drug infusion pumps. Some have also documented attacks on larger pieces of equipment such as MRI scanners.
Many hospitals also fell victim to ransomware attacks in 2016 - software that made their data unintelligible and demanded a payment to restore it to its prior state.
In some cases operations and other procedures were cancelled because computer systems were knocked out by malware.
"As hackers become more sophisticated, these cyber-security risks will evolve," wrote Dr Schwartz.
The FDA pointed out that the rules are not legally binding but instead represent its advice to manufacturers.
However, the guidance said manufacturers had to notify the regulator if a flaw in a product led to someone being harmed or killed.
Security researcher Beau Woods said the FDA had been instrumental in getting healthcare organisations, manufacturers and cyber experts talking about how to tackle and fix vulnerabilities.
"If you look at the general trend over the last few years we are getting better and we are fixing them faster than we were before," said Mr Woods, who is a member of an organisation called I Am The Cavalry that researches and advises on cyber issues that effect public safety.
This had led to many manufacturers adopting good vulnerability disclosure schemes and to some organisations that buy a lot of medical equipment demanding higher standards from their suppliers.
However, he said, the hyper-connectedness of all organisations including hospitals meant devices never meant to be online were now accessible via the net.
Mr Woods said he had seen attacks aimed at stealing personal data accidentally knock out older medical equipment that helped monitor vital life signs.
"It's those types of things that scare me much more than someone lurking in the shadows," said Mr Woods who is deputy director of the cyber statecraft initiative at the Atlantic Council think tank.
The FDA rules have been issued days before the start of the massive CES tech show in Las Vegas.
Gadgets that help people live healthier lives or let them manage chronic conditions, such as diabetes, are expected to feature strongly at the show.


A man has died after he was hit by a car in Derbyshire in the early hours of Sunday.

The accident happened on the A615 Alfreton Road in Tansley when a dark coloured vehicle struck the pedestrian at about 00:30 BST.
Derbyshire Police said the driver of the car stopped at the scene. The injured man was later pronounced dead in hospital.
Witnesses to the incident are urged to contact the force.


Fire crews have been battling a serious blaze which broke out overnight in a warehouse in north-west London.

More than 100 firefighters were sent to tackle the blaze at an industrial unit on Western Road in Park Royal.
London Fire Brigade said the ground floor and first floor were alight and a large section of the roof was also on fire.
The brigade was called at 00:29 BST on Thursday. The cause of the fire is not yet known.
Station Manager Bill Dunn, who is at the scene, said: "The fire is causing a lot of smoke in the Park Royal area and locals should shut windows and doors."
An eyewitness who lives near the scene of the blaze said visibility was down to zero.
"I was woken up by the smoke. My windows were open. I could hear sirens," he said.
"It looked completely foggy outside."
He said the area, close to a petrol station, had been cordoned off.
Mr Dunn said the fire was likely to be a "protracted incident" and would probably cause rush-hour disruption. The public has been warned to avoid the area.
Fifteen fire engines went to the scene from Willesden, Acton, Park Royal, Wembley, Chiswick, Hammersmith, Paddington, and Northholt.

The night before a gunman killed five US service personnel in Tennessee, he sent a text message linking to a religious verse about "declaring war", a report says.

Mohammad Youssuf Abdulazeez also spoke out against conflicts in the Middle East, according to the Reuters agency.
Police have said his motives are still being investigated.
Four US Marines were killed in the shooting. A sailor who was seriously injured died in hospital on Saturday.
Logistics specialist Randall Smith had been fighting for his life since the attack.
Abdulazeez was himself later killed in a shootout with police.
Reuters says it has seen a text sent the night before to a friend linking to a passage of Islamic text - Hadith 38 - containing the verse: "Whosoever shows enmity to a friend of Mine, I will indeed declare war against him."
The friend, who requested anonymity, said he thought nothing of the text at the time, but now wonders if it was a hint at the attack to come.
Full text of Hadith 38
Allah the Almighty has said: "Whosoever acts with enmity towards a friend [wali] of Mine, I will indeed declare war against him. Nothing endears My servant to Me than doing of what I have made obligatory upon him to do. And My servant continues to draw nearer to Me with supererogatory [nawafil] prayers so that I shall love him. When I love him, I shall be his hearing with which he shall hear, his sight with which he shall see, his hands with which he shall hold, and his feet with which he shall walk. And if he asks [something] of Me, I shall surely give it to him, and if he takes refuge in Me, I shall certainly grant him it."
Other friends also told Reuters that Abdulazeez spoke of his anger about conflicts in the Middle East, including Israeli bombing campaigns in Gaza and the civil war in Syria, after returning from a trip to Jordan last year.
"He had always talked about it, but I'd say his level of understanding and awareness really rose after he came back," said one of the friends interviewed.
They said he had purchased three guns online following the visit, and used them for target practice.
"It would be premature to speculate on exactly why the shooter did what he did," FBI agent Ed Reinhold said. "However, we are conducting a thorough investigation to determine whether this person acted alone or was inspired or directed."
Abdulazeez began Thursday's attack with a shooting spree at a recruitment centre in Chattanooga.
He then drove about six miles (10km) to a Navy and Marine reserve centre, where he shot and killed the marines, and wounded Navy Petty Officer 2nd Class Smith.
"A male Navy Petty Officer succumbed to wounds received in the July 16 shooting at the Navy Operational Support Center (NOSC) in Chattanooga, Tennessee" on Saturday at 02:17 local time (06:17 GMT), the US Navy said in a statement.
It did not name the sailor, but family members confirmed it was Randall Smith.
A relative told the US military newspaper Stars and Stripes that Smith was married with three young daughters.


The maker of the Blackberry PlayBook has delayed an update to the tablet computer's operating system until next year.

Research In Motion said it expects to deliver the software in February. It had been due this month.
RIM has admitted that sales of the device are lower than it anticipated. It acknowledged customers want native email, calendar and contacts applications.
The update aims to add the features.
A company blog described the decision as "difficult", but promised the revision will allow the firm's phones and PlayBooks "to work together even better".
RIM's shares closed down 7.5% on the news.
At present users cannot access their Blackberry email through the tablet computers unless the devices are linked to one of the firm's smartphones using its Bridge software.
The Canadian firm also said it had taken the decision to defer the inclusion of a BBM instant messaging application until a later release.
However, RIM said it was still planning to offer businesses the ability to manage their employees' tablets from a centralised computer server and to offer workers custom-built applications through the Blackberry App World store in its OS 2.0 download.
Analysts said the news may prove damaging to sales over the holiday season.
"It is a big setback for them. When they launched the tablet they tried to walk the line between a consumer device and an enterprise device," said Jon Erensen, research director at the technology specialists Gartner.
"People were hoping the initial limitations would be corrected with the update by now. The delay means they fall even further behind."


A 16-year-old has been shot in both legs in a paramilitary-style attack in west Belfast.

It happened in Aitnamona Crescent at 20:50 GMT on Sunday.
He was taken to hospital for treatment to his injuries which are not thought to be life threatening.
Ch Insp Norman Hanslet said: "To shoot anyone is bad enough but this is blatant child abuse and there should be no place for the shooting of a child in today's society."
"I know that the local community abhor this type of behaviour and I would ask people to support and assist police to bring these people to justice."
Police appealed for anyone with information to contact them.


Trading in Avon Products was repeatedly halted earlier on Thursday after shares soared as much as 20% in New York.

Reports of an $8bn (Â£5.1bn) takeover offer - three times its market value - from a firm called "PTG Capital Partners" sent shares in the cosmetics firm on a wild ride.
But Avon said it had not received any offers.
Many on Wall Street doubt whether the firm exists at all, because of the mysterious filing filled with errors.
The document appearing on the website of the Securities and Exchange Commission includes such mistakes as a misspelling of PTG Capital Partners' own name.
There is a well known private equity firm called TPG Capital, and the filing appears to lift information from its website, even referring to the bidding firm as "TPG".
The contacts listed in the filing contain phone numbers that reach generic voicemail messages of the type not normally used by professional businesses.
The BBC's attempts to leave messages at PTG and the firm's supposed law firm, Trose & Cox, were unsuccessful.
Trading in Avon shares was halted three times on Thursday, because of the wild market action.
They climbed 6% higher at $7.07 in Thursday afternoon trading.
Shares of Avon had fallen more than 20% this year before Thursday's volatility.
The company reported an annual net loss last month.


Stories of acts of kindness are emerging in the wake of the Manchester attack, with many people from the community rushing to help - offering free lifts home and rooms for the night.

As hundreds of people fled Manchester Arena following the explosion, taxi drivers began taking people to safety.
Driver AJ Singh said he tried to help wherever he could.
"I've had people who needed to find loved ones. I've dropped them off to the hospital. They've not had any money, they've been stranded," he told Channel 4 News.
"We should come out and show whoever's done this that it doesn't matter because Manchester, we're glue and we stick together when it counts."
Sam Arshad, from StreetCars Manchester asked his drivers to give free rides to anyone stranded after the Ariana Grande concert.
"The audience was a very young audience, and there were a lot of people there without their parents," he told the BBC.
"And it's then that people were requesting taxis but they didn't have money.
"It was at that point that I made the decision that money isn't everything in life and we're part of Manchester and we need to do our part to make sure these people get home safe and sound."
Colin Paterson, the BBC's entertainment correspondent, was standing outside as the audience were running out of the arena.
"As I was standing there a taxi just pulled over a said 'would you like a lift? I'll take you anywhere'," he said.
"There are stories of cab drivers driving over from Liverpool to try and offer people free lifts back to Liverpool.
"There were stories of people coming on to the streets of Manchester to offer their spare rooms because people were not able to get back to their hotels."
Liverpool City Region Metro Mayor Steve Rotheram, whose two daughters and two nieces were at the concert, praised the "spontaneous acts of ordinary people" of Manchester following last night's attack at a concert in the city.
"The spirit that they have displayed is just typical of people in this part of the world," he said.
"A taxi driver from Kirkby fought his way through horrendous traffic and got out of his cab to find my daughters and two nieces. I am forever grateful to that person.
"While I've got huge relief this morning my girls are safe, there will be parents waking up without children and unfortunately children waking up without parents this morning because of this horrendous act."
Praise for these acts of kindness poured in on social media, along with offers of help.
As news of the attack spread, locals soon began offering spare rooms on social media, under the hashtag #RoomforManchester.
Greater Manchester mayor Andy Burnham tweeted: "If you are stranded in the area you can also follow #RoomForManchester where hotels and local people of our great city are offering refuge."
Thousands of people have also turned to social media to find missing relatives and friends - and there are many people who are offering support.
Olivia Campbell Hardy has been missing since last night's concert.
Her mother, Charlotte Campbell, speaking on Radio 4's Today programme said "she's not been found yet" but "she can't thank people enough" for having helped her since her appeal on social media.
Elsewhere, there are reports of cafes offering free drinks for the emergency services, people bringing tea to the police at the cordon and others queuing up to give blood.
Meanwhile, more than Â£50,000 has been raised for a fund to help support the families in the aftermath of the attack, set up only hours ago by the Manchester Evening News.
TV star James Corden shared an emotional tribute to Manchester on social media, saying: "When I think of Manchester, of the place that I know, I think of the spirit of the people there and I'm telling you, a more tight-knit group of people, you will be hard-pressed to find."
Mr Burnham praised the efforts of the community, saying that their efforts demonstrated "the true spirit of our city in the face of such devastating tragedy".
"They responded in the best possible way with generosity, with kindness, that was I think humbling," he said.
"And I think that sends a message to the whole world about what kind of people we are here.
"In this darkest hour - every single person in greater Manchester will be proud that people responded in that particular way and I'd like to thank them for doing that."
Local councillor Bev Craig said: "Mancunians opening their homes to those stranded, and businesses offering free rides. This is the Manchester I love."


A review is being carried out into the care received by a man who killed himself after "begging" to be sectioned but was turned down.

James Thompson's parents believe he might still be alive if he had received better care.
In the weeks before his death in July, the 44-year-old was being treated as an outpatient at the Bradgate Mental Health Unit in Leicester.
Leicestershire Partnership NHS Trust offered its sympathy to his family.
His mother, Margaret Timson, said: "He did beg on numerous occasions for them to section him and the answer every time was 'It's not a place you would like to go to'.
"I think, had he had some help and been taken in, he might be here today."
His stepfather Bill Timson said: "He was assessed at least three or four times.
"They should have been able to pick up that there is something wrong here, he is going to do something, he is in danger of harming himself, we need to take him away."
Mr Thompson attempted suicide more than a dozen times before his death on 16 July.
He had been diagnosed with bi-polar disorder as well as other mental heath conditions and was also an alcoholic.
His mother said: "Part of me thought I knew this was going to happen, and it did, because he had no continuous help from any of the services.
"I feel he was let down."
Leicestershire Partnership NHS Trust said it was not in a position to comment fully because an inquest is yet to be held.
A statement said: "Our staff are committed to providing the best care possible and we are carrying out an in-depth multi-agency review of his care to examine where we might identify any lessons to be learned and what action might be needed to address these."

Accrington made it seven games unbeaten as they brushed aside Luton.

The visitors took the lead when Josh Windass burst down the right wing, before crossing for Scott Brown to turn in from close range.
Luton were unable to respond, and saw efforts from Windass and Terry Gornell go narrowly wide as they struggled to keep out the visitors.
Accrington sealed the win when Gornell met Tariqe Fosu's excellent cross with a glancing header.
Accrington rise into the automatic promotion places, two points clear of the play-offs with five games to go.


These are the darkest days Belgium has known since World War Two, according to one Belgian politician.

The attacks, claimed by jihadist group Islamic State (IS), murdered people at Brussels international airport and on a metro train in the heart of the Belgian capital.
And the targets were among the most sensitive in Europe. Brussels is home to the EU, Nato, international agencies and companies, as well as Belgium's own government.
Not only is Brussels a high-profile target for Islamists, Belgium has struggled with Islamist groups for years and some 500 of its citizens have been lured into fighting for IS in Syria and Iraq.
Several cities have housed Islamist cells, but the most active have been in Brussels and in the south-western suburb of Molenbeek in particular - an area with a high ethnic Moroccan population and a high rate of unemployment.
Several of the bombers and gunmen who targeted Paris last November, killing 130 people, had been living in Molenbeek. The main suspect not to die in the Paris attacks, Salah Abdeslam, returned to Belgium the day afterwards and managed to evade police until 18 March. He and an accomplice were captured alive, again in Molenbeek.
Many Belgians were expecting a response from jihadists. "I had certainly expected something else would take place, but not that it would happen on this scale," says Belgian jihadism expert Pieter Van Ostaeyen.
More Belgian Islamists have gone to fight for IS than from any other European country per capita. Almost half have come from Brussels.
But it is not just Brussels, and Molenbeek in particular, that has had a problem with jihadism.
Islamists have also emerged from other Belgian cities, including Verviers and Vilvoorde and most significantly Antwerp, where the now disbanded group, Sharia4Belgium, recruited the first Belgian fighters for Syria.
Many trace Belgium's problem with Islamism to its decision in the 1970s to allow Saudi Arabia to construct the city's Great Mosque.
The Saudis also sent over a large number of imams to preach a hardline, Salafist form of Islam to a recently arrived Muslim population.
Critics believe the Salafist influence, combined with a lax approach by authorities over a 20-year period, helped jihadism to spread.
And then there was anger when the government changed tack, banning women from wearing a full Islamic veil in public.
The Belgian connection
Belgian's jihadist networks
So were Tuesday's bombings retaliation for last Friday's success in capturing two Islamists alive? The arrests were clearly a blow to IS and Belgian jihadists.
Abdeslam has been described as the logistics expert in the Paris attacks. He rented flats, drove militants across Europe and bought bomb-making equipment. Days before his arrest, an accomplice who had been hiding with him, Mohamed Belkaid, was shot dead by police. He had been wrapped in an IS flag.
"What seems likely is that attacks were already being planned and due to specific arrests they were accelerated because the terrorists knew they were being hunted," says Prof Dave Sinardet of Vrije Universiteit Brussel (Free University Brussels).
In fact Brussels had already tried to guard against multiple attacks following an apparent threat 10 days after the Paris attacks. For several days the city went into lockdown, much as it did on Tuesday, with public transport at a standstill and people told to avoid travelling around.
Three men with suitcases packed full of explosives were able to enter the airport at Zaventem and blow themselves up. An hour or so later another man was able to enter a metro train a stone's throw from the headquarters of the EU and blow himself up.
Security forces had a dry run in November, the terror threat was at its second highest and soldiers were already deployed on the streets of several cities.
A beleaguered police force has clearly buckled under the weight of an almost non-stop Islamist threat. And yet it suffers from institutional problems too.
Brussels is a relatively small European capital, and yet it still has six police zones. Its CCTV system is far less developed than London or Paris.
"It's clear there are inefficiencies in the level of security services. For years we haven't put enough energy into issues of security and terrorist threats," says Prof Sinardet. However, he argues this kind of terrorist attack is very difficult to avert, as witnessed in Madrid, London and Paris.
For Belgians, this is the most awkward question. Several suspects are still urgently being sought by police.
One of the suspected airport attackers (the man in the hat on the right of the picture) was on the run on Tuesday and police were already actively hunting two other suspects who were both accomplices of Salah Abdeslam.
One of the missing Paris suspects is Mohamed Abrini, and nothing has been heard of him since November last year.
It is unclear if another Paris suspect, Najim Laachraoui, is still alive. Unconfirmed reports suggest he blew himself up in the airport attack. His fingerprints were found in the Brussels flat where Paris bombs were made, and he may have been the bomb-maker.
After the Paris attacks, US counter-terrorism expert Clint Watts wrote of the "iceberg theory of terror plots": for every attacker, there were usually several others helping to facilitate the plot, but what one saw was just the tip of the iceberg.
Mr Watts believes that the Brussels bombings are the fallout from the Paris attacks. What is not clear is whether those still on the run plan further bloodshed.


At 1pm every afternoon, the hustle and bustle of Real Madrid's Valdebebas training ground grinds to a halt and the facility resembles a ghost town.

A silence descends over the complex for the following two hours as players and staff close their eyes and drift into a siesta before waking and resuming their day - but they're not sleeping on the job.
The scene is a window into football's relentless pursuit of marginal gains as clubs across Europe turn to technology, purpose-built facilities and sleep experts to recharge their multi-million pound assets and gain a competitive advantage.
Tennis great Roger Federer and basketball star LeBron James are both advocates of sleeping for upwards of 10 hours per night and research shows the performance benefits of proper rest for athletes.
A study by Stanford University sleep expert Cheri Mah showed basketball players who increased their sleep duration to those levels improved shot accuracy by 9% in tests and recorded improved sprint and reaction times.
Take recovery for granted and the risks are great. One restless night is enough to weaken the immune system and increase the risk of illness. Sleep poorly for 64 hours or more and strength and power is reduced.
Fatigue, often brought on by a number of games in a short period of time, increases levels of the hormone cortisol. This can then see the body begin to eat into its own protein stores and reduce a player's muscle mass, heightening the risk of strains and tears.
The brain's ability to send messages to and from different parts of the body to control movement also decreases, which impairs the sense of where limbs are positioned and the perception of strength of effort - making injuries such as ankle sprains more likely.
Those factors prompted Real's sports scientist and conditioning coach, Englishman Jack Nayler, to invite elite sport sleep coach Nick Littlehales to the club in December 2013 to deliver a workshop to manager Carlo Ancelotti and his squad.
Littlehales began his work in the field prescribing specific mattress types to Gary Pallister and Ryan Giggs at Manchester United in the mid-1990s in a bid to cure their respective back and hamstring problems.
He has since gone on to work with the England football team, Team GB, 2012 Tour de France winner Sir Bradley Wiggins and a host of Premier League clubs, including Manchester City, Arsenal, Chelsea and Southampton.
At Madrid, he inspected each of the 81, five-star, fingerprint-accessed bedrooms at the club's training complex to evaluate the 'sleep environment' - a term he's coined to represent the temperature, lighting, air quality, duvet-type and mattresses inside the rooms.
After delivering his seminar to Cristiano Ronaldo and his team-mates, Littlehales was approached by Wales forward Gareth Bale, who requested a one-on-one consultation.
With Nayler and the club's doctor also present, the former Tottenham forward went through an examination to establish his body characteristics (height, weight and any injury problems), daily routines (usual wake and sleep times), activities (types/intensity of training each day), sleep habits, chronotype (the natural time he sleeps and wakes), and formulate a sleep profile - an in-depth report covering the areas in the graphic below.
"Gareth had only just joined the club and he had a lot of new stuff to deal with," Littlehales told BBC Sport. "He identifies with being an owl - he hates the mornings. He's also got a young child, which can have an effect on sleep."
Bale's biological clock - or circadian rhythm to give it its proper title - means he naturally falls asleep and wakes up at later times, leaving his energy levels at their lowest early in the morning, before peaking in the afternoon.
It's a problem Littlehales has encountered with countless athletes and in a bid to combat disruption to the body's preset patterns - which can also occur following European fixtures which finish late in the evening - he recommends naps.
One player he worked with at Manchester City told him of his routine in the aftermath of Champions League games, which would see him stay up until 4am as he struggled to get to sleep with the adrenaline from the game still in his system.
"He'd stay downstairs on the Xbox until the early hours. He'd fall asleep on the sofa and wake up mid-morning because he didn't have training the following day - he was completely out of sync," Littlehales said.
"Your body has two in-built nap times when energy levels dip - the first between 1pm and 3pm and the second between 5pm and 7pm.
"Now he just works around the kick-off. Before and after the game he has a routine. If he's got a 7:45 kick off at home, his bed time is 2am. He gets up at 6:30 and has breakfast. If he's still tired, he'll have a 90-minute nap at those times and catch up with his sleep that way."
At Southampton, no stone has been left unturned in the quest for a perfect night's sleep. Every morning, each member of the squad uses a bespoke wellbeing app to fill in a questionnaire on their own personal tablet given to them by the club.
Players are asked to mark their quality of sleep, mood, muscle soreness and general level of fatigue out of 10. If the level of sleep is below an individual's threshold  they will begin using devices to monitor them at night.
The club's head of sports science, Alek Gross, told BBC Sport: "We do have players who have been prescribed individual sleep kits to aid their sleep throughout the week. They'll have a specific duvet and pillow thickness, perhaps blackout curtains that are specific to their needs.
"Temperature in hotel rooms is more of a problem. Ideally it needs to be 16-18 degrees. Players have their own room on trips now so we can really tailor to each individual.
"We advise the players against looking at mobile phones and television screens 90 minutes before bed - even the red light on your TV can affect your circadian rhythm and keep you awake."
Players also have a list of prohibited foods and drinks they are warned against consuming in the evening. Caffeine and liquids high in sugar are off the menu, as are fat-laden meals, which take longer to digest and raise body temperature, which in turn slows the process of falling to sleep. All players are given a milk-based protein drink to aid recovery and induce sleepiness.
Attitudes towards sleep in football are changing. Manchester United installed sleep pods at the club's Carrington training ground for players to nap in between double sessions during the summer, while Manchester City's new £200m complex has 32 en-suite bedrooms each decorated with sleep-inducing wallpaper - a light green design with ever decreasing circles.
At Liverpool, players use various types of monitoring technology to detect movement during sleep, including wrist devices and heart-rate straps.
The club's sports science consultant, Barry Drust, said: "We've adopted a lifestyle-orientated approach. It isn't standard for all the players at Liverpool to have their sleep monitored but it does happen relatively frequently with individuals, depending on the situation.
"Football is a team sport, but it's a team sport made up of individual athletes, so the philosophy at Liverpool is much more about trying to create individual strategies for individual players."
In October Liverpool manager Brendan Rodgers applauded Raheem Sterling's maturity in complaining of tiredness to England boss Roy Hodgson and sitting out the 1-0 win over Estonia - it might just be a sign of things to come as players look to sleep their way to the top.


Moderate Republican New Jersey Governor Chris Christie has won a landslide re-election, a possible launch pad for a 2016 White House run.

In Virginia, Terry McAuliffe - a key Hillary Clinton ally - narrowly beat a Republican to become governor of the pivotal presidential swing state.
Bill de Blasio's thumping victory in New York makes him the city's first Democratic mayor-elect in two decades.
Tuesday's results point the way to next year's US midterm elections.
New Jersey's straight-talking Governor Christie brushed aside his Democratic challenger, state senator Barbara Buono, by 60.5% to 38%, retaining a handy platform for a potential presidential bid.
His ability to attract the support of Democrats, independents and minorities makes him a tantalising prospect for the ideologically split Republican party ahead of 2016.
By Mark MardellNorth America editor
"We stand here tonight showing that it is possible to put doing your job first," said Mr Christie in his victory speech, "to put working together first, to fight for what you believe in yet still stand by your principles and get something done for the people who elected you."
The governor, known for his readiness to work with Democrats in a left-leaning state, won much praise for his handling of the carnage wrought on the region by super-storm Sandy one year ago.
However, fellow Republicans at a national level lambasted him for his embrace of Democratic President Barack Obama as he visited Jersey Shore to see the devastation.
In the Virginia governor's race, Mr McAuliffe eked out a smaller-than-expected, 48% to 45.5% win against socially conservative Republican Ken Cuccinelli.
"Over the next four years most Democrats and Republicans want to make Virginia a model of pragmatic leadership," said Mr McAuliffe, a Democrat taking charge in a state with a Republican-led legislature. "This is only possible if Virginia is the model for bipartisan co-operation."
During the campaign, Mr McAuliffe had emphasised his opponent's tea party support. The hardline wing of the Republican party was widely blamed for last month's government shutdown, which temporarily laid off many of the federal workers who populate Virginia's suburbs.
Mr Cuccinelli, the state's outgoing attorney general, had stressed his Democratic rival's championing of the Obama healthcare law, whose troubled rollout has been a White House public relations disaster.
A Libertarian candidate who won nearly 7% of Virginia's vote may have cost the Republican the race, say analysts. Mr Cuccinelli was also vastly outspent by his Democratic opponent.
Mr McAuliffe is a veteran Democratic party fundraiser who was chairman of former Secretary of State Hillary Clinton's 2008 presidential campaign.
Profile: Bill de Blasio
His capture of the governor's mansion in a crucial presidential swing-voting state could help plot a road map to victory for her should she run again for the White House, say analysts.
Meanwhile, Mr de Blasio will succeed New York Mayor Michael Bloomberg to become the first Democratic mayor of America's largest city since 1993.
He secured a whopping 73% of the vote, compared with 24% for his Republican rival, Joe Lhota.
In his victory speech, Mr de Blasio said the result showed that America's largest city had chosen "a progressive path", and he promised to make fighting income inequality his top priority.
In other elections across the US on Tuesday:
Tuesday's off-year polls could be seen as a litmus test of the parties' support ahead of the 2014 midterm elections.
Next year's votes will decide the make-up of the House of Representatives, one-third of the Senate, and governorships in more than half the states.
Mr Obama's Democratic party controls the US Senate, while Republicans hold sway in the House of Representatives.
Now in his second term, Mr Obama will vacate the presidency in 2017.
Joseph Lhota (Republican): 24% - Bill de Blasio (Democrat): 73%
Chris Christie (Republican): 60.5% - Barbara Buono (Democrat): 38%
Ken Cuccinelli (Republican): 45.5% - Terry McAuliffe (Democrat): 48%


Bournemouth striker Callum Wilson is out for at least six months after injuring his knee against Stoke on Saturday.

Scans revealed the 23-year-old ruptured the anterior cruciate ligament in his right knee and he will have an operation next week.
Wilson had made an impressive start to life in the Premier League, scoring five goals in seven games.
He scored a hat-trick in a 4-3 win against West Ham in August.
"It's very disappointing for Callum, after what has been an exceptional start to the season, but I am sure he will come back fitter and stronger," said Bournemouth manager Eddie Howe.
"Callum is the type of character who won't be fazed by such a setback, and I am sure he will turn this experience into a positive in the long run.
"As I have said many times before though, this kind of setback offers others the opportunity to step up to the plate, show everybody what they can do and make a real impact at this level."
The news is the latest blow for the Cherries following long-term injuries to defender Tyrone Mings and winger Max Gradel.


Scotland Women will face England in their first match of Euro 2017 in the Netherlands next summer.

The Scots, ranked 21st in the world, will play fifth-ranked England - the group's top seeds - on Wednesday, 19 July in Utrecht.
"So many of our players play in England and have best friends in the England team," said head coach Anna Signeul.
"So I think they will be very excited. I hope it is very motivating for them. It is something to look forward to."
Signeul believes Scotland "couldn't have asked for anything better" in terms of "getting a little bit of attention around the tournament" by drawing England first up.
Her side will then play Portugal, ranked 40th, in Rotterdam on Sunday, 23 July.
Their final group game will be against Spain, ranked 14th, in Deventer on Thursday, 27 July.
"They are two teams we have to watch out for," Signeul told BBC Scotland. "We know they have developed a lot.
"Spain have had huge success on the youth side and their young players are coming through to the senior team and showing a lot of progress.  So we have two very difficult teams there as well.  It is an interesting and exciting group."
It is Scotland's first time at a major finals after 13 failed attempts, having finished runner-up to Iceland in their qualifying campaign.
Despite a convincing qualifying campaign in which Scotland won seven and lost one of their eight games, they were beaten 7-0 in a home friendly by Euro hosts the Netherlands in October, underlining the scale of the challenge to progress to the knock-out stages next summer.
"When you look at the draw and the 16 teams, you realise how big this tournament has become and how many good teams there are in Europe now playing women's football, competing at the highest level," Signeul added.
"Germany, England, France and Holland are all very, very strong and it will take a lot for us to be able to compete, but we are going to try."
Group A: Netherlands, Belgium, Denmark, Norway
Group B: Germany, Sweden, Russia, Italy
Group C: France, Iceland, Austria, Switzerland
Group D: England, Scotland, Spain, Portugal


Wigan Athletic manager Gary Caldwell hopes his side can earn a convincing return to the Championship.

The Latics, who were relegated last season, are second in League One and a point behind leaders Burton.
"I am very fortunate that I have got a good group of players and squad to pick from," he told BBC Radio Manchester.
"I don't worry about this group. They have shown time and again their character and determination to win and take this club back up the leagues."
Former Scotland defender Caldwell continued: "I hope we do it (win automatic promotion) convincingly. At the minute we're a team full of confidence and belief, and we'll continue to do that."
Monday's 1-0 win against Rochdale, which came three days after a 4-1 win away at Swindon, extended Wigan's unbeaten run in League One to 18 games.
"We have to recover from what is a very difficult period," Caldwell added. "To play two games in three days is a big ask physically."
Caldwell's side were forced to work for their three points in an edgy 1-0 win against Dale, who played for nearly an hour with 10 men after Ian Henderson was sent off for kicking out at Jason Pearce.
"I would be very disappointed if any of my players reacted the way their player reacted, you can't do that in football, everyone knows that," he said.
"At home it can be difficult against 10 men at times. It galvanises the away team and it did that with Rochdale who had great desire."


Entertainer Michael Barrymore's arrest over the death of a man at his home was unlawful because the officer involved had not been fully briefed, court papers filed by Essex Police admit.

The former star is suing the force for damages after he was detained in 2007 over the death of Stuart Lubbock.
Mr Lubbock was found dead in a swimming pool at Mr Barrymore's home in 2001.
In High Court documents, the force admits the detective who was supposed to arrest the star was delayed.
The force said it wanted to question Mr Barrymore, whose real name is Michael Parker, and two other men over the rape and murder of Mr Lubbock after new evidence emerged.
Post-mortem tests found the 31-year-old butcher had suffered severe internal injuries indicating sexual assault and his bloodstream contained ecstasy, cocaine and alcohol.
Mr Barrymore and the other men were arrested and later released without charge.
In its defence document, Essex Police said: "The arrest of the claimant was unlawful only by reason of the fact the arresting officer, PC Cootes, was not fully aware of the grounds for arrest... and not by reason of a lack of reasonable grounds to suspect the claimant."
PC Cootes, who was carrying out covert surveillance at the property where Mr Barrymore was staying in 2007, was ordered to make the arrest when the designated officer, Det Con Sue Jenkins, was delayed.
"Since the claimant would have been lawfully arrested but for the said delay, he is entitled only to nominal damages for false imprisonment," the defence document added.
Mr Barrymore's lawyers said police did not have reasonable grounds for suspecting him of the rape or murder of Mr Lubbock, and the arrest was unlawful and "wholly disproportionate and unreasonable".
Their court documents also said Mr Barrymore "suffered loss and damage namely distress, shock, anxiety and damage to his reputation".
He has also claimed his career suffered because of the police handling of the case.
Essex Police said if earnings had been lost, it would be because of "matters outside the defendant's control", including that a young man had been found dead in his swimming pool which had "inevitably" led to a police investigation and inquest.
A decision will be made in the New Year by a High Court judge about compensation Mr Barrymore may receive.


A European Commission study has found that jobless EU migrants make up a very small share of those claiming social benefits in EU member states.

The study, carried out by a consultancy for the EU's executive, suggests that claims about large-scale "benefit tourism" in the EU are exaggerated.
But the UK government still wants tighter EU rules on access to benefits.
In most of the EU countries studied the portion of EU migrants among welfare beneficiaries was below 5%.
The European Commission says EU migrants continue to make a net contribution to their host countries' finances, by paying more in taxes than they receive in benefits.
According to the latest report, jobless EU migrants form 1% of the total EU population. In the UK the figure was 1.2% in 2011 and 2012.
"The study found little evidence in the literature and stakeholder consultations to suggest that the main motivation of EU citizens to migrate and reside in a different member state is benefit-related, as opposed to work or family-related", the study by consultants ICF-GHK said.
It looked at non-contributory cash benefits across the EU and access to healthcare - that is, benefits that do not depend on a person's national insurance contributions.
EU membership gives citizens across the 28-nation EU the freedom to move to another EU state, work there and claim benefits, though conditions vary considerably from country to country. Most EU countries are in the Schengen zone, where border checks are minimal.
The new study was based on survey data, including case studies, and national administrative records. The consultancy pointed out, however, that there is a lack of official data on non-active EU migrants, so many of the figures are estimates.
In the UK much debate has focused on migrants' access to the National Health Service, which provides universal care and is funded by UK taxpayers.
According to the EU study, non-active EU migrants account for 0.2% of total health spending in the EU, on average.
Responding to the study, a spokesman for UK Prime Minister David Cameron said there was "widespread and understandable concern" about benefit tourism and the UK was working with other EU countries to change the rules on access to benefits.
"There is an issue around access to the welfare system, around fairness as well as a cost issue... We don't think the current system is working," he said.
In 2003-2012 there was a rise in the total number of intra-EU migrants - from 1.3% to 2.6% of the total EU population, according to the EU study.
That period covers the EU's eastward enlargement and the eurozone debt crisis - developments which have spurred migration from parts of eastern and southern Europe.
At the same time, the rate of "economic non-activity" among EU migrants fell to 33%, from 47%.
More than two-thirds of non-active EU migrants are pensioners, students and jobseekers, rather than migrants' relatives or "homemakers", the study found.
The highest numbers of non-active EU migrants, per head of population, are in Luxembourg (13.9%), Cyprus (4.1%), Belgium (3%) and the Republic of Ireland (3%).
The proportion of young, working-age people among EU migrants tends to be higher than in the host country's general population.
The EU's eastward enlargement in 2004 and 2007 brought in 12 new member states, mostly former communist countries lagging behind the other EU members economically.
The number of jobseekers from Poland and other East European countries who came to the UK after 2004 was far greater than the Labour government in power at the time had anticipated.
Next year the EU labour market will be opened fully to Bulgarians and Romanians - whose countries joined in 2007. That has fuelled concern in the UK about a possible surge in the numbers of Bulgarians and Romanians moving to the UK.


Roger Federer is one win from a historic eighth Wimbledon title after beating Czech 11th seed Tomas Berdych in straight sets in the semi-final.

Media playback is not supported on this device
The Swiss, 35, won 7-6 (7-4) 7-6 (7-4) 6-4 to reach his 11th Wimbledon final, having last won the title in 2012.
He will face Croatia's Marin Cilic after the seventh seed beat American 24th seed Sam Querrey 6-7 (6-8) 6-4 7-6 (7-3) 7-5 on Centre Court on Sunday.
Cilic, 28, is into his second major final after winning the 2014 US Open.
"It's unbelievable," said Cilic, the second Croat to reach the men's final after Goran Ivanisevic won in 2001.
"I've been playing really great tennis."
Federer has already added to his lengthy list of achievements by reaching a record 29th Grand Slam final, becoming the second-oldest man to do so after the 39-year-old Ken Rosewall reached the 1974 Wimbledon final.
Having waited five years to win his 18th major title at this year's Australian Open, Federer could make it 19 only six months later.
"I feel very privileged to be in another final," he said.
"I've got the pleasure to play on Centre Court another time. I can't believe it's almost true again. I'm happy to have a day off to reflect on what I've done at the tournament."

Federer had won his past seven matches against Berdych, and 18 of 24 in all, but the Czech made him work for number 19.
There were just three breaks of serve over two hours and 18 minutes, two for Federer, who hit 53 winners to Berdych's 31 in a high-quality contest.
After dropping only one point on his serve as he eased 4-1 clear, Federer offered up two double faults that allowed Berdych to peg him back and earn a tie-break.
Again Berdych came back from an early deficit to trail 4-3 but a forehand error returned the advantage and Federer capitalised to clinch the set.
It was a blow for the Czech, but he fended off break points early in the second and kept pace with the seven-time champion.
Federer needed to produce a magnificent dipping forehand winner to hold serve at 3-3, and it was the same shot that would dominate the second tie-break.
Four brilliant forehands in a row gave the Swiss a 5-1 lead that proved enough for a two-set lead, and there was more magic off that wing in the third.
Berdych saw a chance to extend the contest disappear when Federer saved two break points with successive aces before breaking in the next game.
At 5-3, the Swiss produced a stunning forehand flicked pass that had the 15,000 spectators on Centre Court gasping, and moments later he served out victory in his 42nd Grand Slam semi-final.
Federer saved a match point on his way to beating Cilic in last year's quarter-finals, and said: "Last time we had a brutal match - I was two sets down. I had to get lucky to win.
"Marin is a great guy. He's a lovely guy, in his first Wimbledon final.
"He crushed me at the US Open a few years ago. I hope he doesn't play that good."

Boris Becker, three-time Wimbledon champion
Usually cars have five, maximum six gears - Roger Federer seems to have 10 gears. Whenever he's in trouble he comes out with an even better shot.
All credit to Berdych - he really took it to him and played great under pressure - but every time we thought he had a little bit of a chance Roger was just coming up with another magical shot.
That's what makes him the greatest of all time - to do it over such a long time. At 35, potentially playing your best tennis, who would have thought that?

Querrey, 29, had played three successive five-set matches to reach his first Grand Slam semi-final, and almost forced a fourth before Cilic finally saw off the American's challenge.
Both men had more than 100 aces to their name heading into the semi-finals, and it was the Croat who had more success in breaking down the big serve.
Cilic won more than twice as many points on return and earned 14 break points to Querrey's three, but the American saved 10 and was two service holds from taking it to a fifth set.
He edged the first set from 4-1 down in the tie-break before Cilic earned the first break of the match at 3-3 on his way to levelling at one set all.
The match was over two hours old before two loose shots from Querrey - a backhand error followed by a forehand into the net - separated the pair in the third set tie-break.
The pair's previous meeting at Wimbledon in 2012 lasted over five hours and finished 17-15 to Cilic in the fifth set, and when a wayward Cilic smash helped Querrey move ahead in the fourth, another final set seemed inevitable.
However, Cilic played a fine game to level at 4-4 with a drop volley and an attacking return of serve, and avoided the need for a third tie-break when he earned two match points at 6-5 and found a forehand winner on the second.
"Sam was playing high-level tennis, especially in the first set," said Cilic.
"I was 4-1 up in the tie-break and didn't convert. After that I was better in the return games. The level was really high."


Archers actress Sara Coward, who is terminally ill, says she hopes the BBC radio soap does not write her character out of the programme.

Coward, 68, was given three months to live in September after she was diagnosed with an inoperable cancer.
"I would prefer it to be over quickly," the actress told Radio Times, when speaking about her illness.
"I don't know what they're going to do with the character [Caroline Sterling] but I hope they don't write her out."
She added: "I'd like them to find someone else to play her. In fact I know the very person; Michael Cochrane's wife Belinda Carroll would be perfect."
Cochrane plays Coward's husband on the long-running Radio 4 programme.
Coward has played Caroline for nearly 40 years but said she has "no interest in being remembered".
The actress is philosophical about her illness.
"I have a lovely array of friends, and a rescue lurcher called Sati, who I adore. I've been very lucky, and it doesn't worry me that my life is coming to an end."
On The Archers website, Coward spoke of her feelings about the character she first played in 1979: "I'm very fond of Caroline. She hasn't had an easy life, in spite of her privileged upbringing, and has been much maligned. 'The bicycle of Ambridge' - really! The poor girl was only trying to find the right man; she just happened to search in some pretty peculiar places."
The character has spent the last few months living in Italy while Coward has been ill.

A teaser from the self-titled "biggest rock star in the world" is always bound to get people talking.

Kanye West has tweeted a cryptic link to a site called Yeezy.Supply and a time code counting down to 21:00 GMT on 12 February.
The page contains no other clues about what will happen at that time, revealing nothing more than a ticking clock and an industrial sounding montage of buzz.
So what could it be?
Not completely out of the realm of possibility, but it is pretty unlikely.
The post follows recent collaborations with Paul McCartney and Rihanna on Only One and FourFiveSeconds as well as reported leaks of previously unreleased tracks.
West played FourFiveSeconds at the iHeartMedia Music Summit in January, but, at the time of release, there was no indication of whether it will appear on Kanye's or Rihanna's next album.
But if Theophilus London's Instagram feed is anything to go by, the follow-up to 2013's Yeezus is ready to go.
In October the rapper posted a picture with West and wrote: "I only remember Kanye playing his new album three times in a dark room of 20 people last night and moshing drunk with mad babes."
For all we know he could be planning to follow Beyonce with a surprise release but the use of the word "supply" and a recent announcement from Adidas suggest Yeezy has something a little more commercial up his sleeve.
Well maybe not leather black jeans on, probably leather black sneakers on.
It's more likely that Kanye's countdown is linked to his recent announcement that he'd be partnering with Adidas for a new project after cutting his ties with Nike.
Earlier this week, it was reported that his new trainer collection would launch on 12 February at New York Fashion Week - the day the timer runs out.
It's also no secret that the rapper is big on his fashion, especially trainers.
In THAT interview with Zane Lowe, Kanye said he had dedicated the last 10 years of his life to fashion and that "no-one can say that I don't know how to design a guy's sneaker".
With a level of dedication that saw him being "kicked out of class for drawing Jordans" at school, it wouldn't be much of a surprise if Mr West was excited enough by his own trainer launch to make an entire website and start a week long countdown ahead of the release.

The death of a six-year-old girl from suspected choking while on holiday in Gwynedd has prompted a call for increased ambulance staffing in rural areas.

Jasmine Lapsley was treated by paramedics in Morfa Nefyn on Tuesday night but could not be saved.
The Welsh Ambulance Service said first responders arrived within 16 minutes - double its eight-minute target.
Councillor Liz Saville Roberts said help should have arrived sooner.
The alarm was raised at 20:30 BST on Tuesday and two community first responders, two ambulances, a rapid response vehicle and an RAF helicopter were sent to the scene.
The ambulance service said it was investigating its response to the incident.
Its target is to reach 65% of the most serious and immediately life-threatening calls within eight minutes.
Ms Saville Roberts, who represents the Morfa Nefyn ward, said paramedics should have been closer to hand, claiming the area's population was four times higher in summer.
"My real concern is the level of staffing we've got on shift for rural areas," she said.
"First responders (trained local volunteers), in this sort of accident, are not going to be able to do anything... they need a paramedic.
"We need a proper picture of the sort of service that's being provided in rural areas."
The Welsh Ambulance Service declined to comment.
Jasmine's home town has not been revealed, but she was not local to the area.
An investigation into her death has been launched by North West Wales Coroner Dewi Pritchard-Jones.


Two Scotland Yard detective constables and a former detective inspector have been named as "key culprits" in bribery allegations revealed to MPs.

The Home Affairs Select Committee was told about "apparent corruption right at the heart of New Scotland Yard".
Officers investigating Nigerian fraudster James Ibori were accused of taking cash payments for information.
The former inspector has denied any wrong-doing and the two serving officers have declined to comment.
The allegations surfaced during a parliamentary hearing on the role of private detectives.
During evidence from lawyer Mike Schwarz from solicitors Bindmans, MPs were told of documents which allege that private investigation firm, Risc Management Ltd, was involved in "wining and dining and paying" officers working on the James Ibori case.
Ibori was the former state governor of the oil-rich Delta region in Nigeria, a corrupt official who stole hundreds of millions of pounds from his homeland.  He was sentenced to 13 years imprisonment last month after pleading guilty to laundering millions of pounds in the UK.
Mr Schwarz, representing Ibori's London lawyer who was jailed as part of the case, said: "The key culprits appear to be the key players who are the senior investigating officer, DI Gary Walters, and two of the key investigators who are DC John McDonald and DC (Peter) Clark."

Ex-governor jailed for Â£50m fraud
Mr Schwarz told the committee there were records that "show about half a dozen payments totalling Â£20,000 over eight or nine months."
The allegations were originally made in an anonymous bundle of documents sent to former Metropolitan Police Commissioner Sir Paul Stephenson and the Independent Police Complaints Commission (IPCC) last summer.
In October last year, the IPCC instructed the Metropolitan Police's Directorate of Professional Standards (DPS) to conduct an internal investigation.
The paperwork included what purported to be detailed invoices and expense ledgers from Risc Management Ltd, headed at the time by two former Scotland Yard detectives, Keith Hunter and Cliff Knuckey.
Among the entries in the documents are details of what were said to be payments made to sources for confidential information about the on-going police investigation into Ibori.
One entry, dated shortly before police were due to interview James Ibori's London solicitor, reads: "Engaged with source in eliciting information re: forthcoming interviewing strategy to de (sic) deployed by police."
Immediately below, the entry states: "Cash payment made to above source for information provided. Â£5,000.00."
The DPS has said it has "an open mind" as to whether the documents are genuine or an elaborate forgery designed to pervert the course of justice.
Mr Schwarz criticised the internal inquiry into the corruption allegations as having "huge failings".
"Two of the key officers are still on duty on the same case and one has retired and joined Risc Management," he told the committee.
In a statement the Metropolitan Police said: "The MPS is investigating an allegation that illegal payments were made to police officers for information by a private investigation agency.
"The DPS referred the matter to the IPCC in October 2011 which agreed to supervise a DPS investigation into the allegations.
"This is an ongoing investigation and it would be inappropriate to comment further at this stage whilst the investigation is under way."
The BBC has confirmed that in the seven months since the DPS inquiry was launched, neither Risc Management, nor the law firm who hired them on behalf of James Ibori, have been contacted. No police officer has been asked about the allegations.
Already under fire for not properly investigating allegations of phone hacking, and with officers facing allegations they accepted cash from News International journalists, the new claims heap further pressure on the Metropolitan Police.
It is not possible to be certain whether the documents at the heart of the corruption allegations are genuine or elaborate fakes nor whether corrupt payments were actually made.
Risc Management denies it has ever paid money to any police officer.


Reconviction rates for offenders in Scotland have fallen to their lowest level for 17 years, figures reveal.

In the year 2013-14, just over a quarter (28%) of offenders were reconvicted within a year.
Those released from short jail sentences - three months or less - were more likely to reoffend than those given longer prison terms or sentenced to community payback orders.
The Scottish government said the figures were "encouraging".
The biggest improvement on reoffending was for younger offenders.
Over the past 10 years, the average number of reconvictions per offender dropped by nearly a third for offenders aged 21 to 25.
On average, those who were sentenced to six months or less in prison were reconvicted twice as often as those given community payback orders, the most common type of community sentence.
While the number of reconvictions for people on Drug Treatment and Testing Orders (DTTOs) rose last year, the rate has dropped by a third over the past 10 years.
Justice Secretary Michael Matheson said: "Today's figures show we are continuing to make good progress on tackling reoffending - a key goal of this government's justice strategy.
"The continued fall in reconvictions is testament to the work done by our police, courts and other partners in communities across Scotland to prevent offending and, where crimes do occur, stop people going on to commit further offences."
The justice secretary added: "I have set out my vision for a Scotland where people are held to account for their offending and are then given the opportunity to change their lives and become active members of society.
"The evidence backs up our approach that robust community sentences, such as CPOs, are more effective at reducing reoffending than short custodial sentences."
He added: "Today's statistics build on the strong work being done in Scotland's justice system, with recorded crime at a 41-year low, youth offending and knife crime down and an end to automatic early release for all long-term prisoners.
"It is encouraging to see but we will not be complacent in our efforts to reduce crime even further."


The Revolution, Prince's backing band during the 1999 and Purple Rain era, will reunite for a pair of tribute shows honouring the late music star.

The group will play at the First Avenue club in Minneapolis - which was the partial setting of the Purple Rain film - on 2 and 3 September.
Key members Wendy Melvoin, Lisa Coleman, Brown Mark, Bobby Z and Matt "Doctor" Fink will all take part.
Announcing the shows, they called Prince's death a "profound loss".
"Only by playing for you, the fans, can we be Prince's Revolution," they added. "He gives us to one another now, as we all start to heal and fill forever emptiness with sound. Together we are The Revolution."
Bassist Brown Mark hinted more dates could be announced soon, writing on Facebook: "Minneapolis First Avenue is just the beginning."
First Avenue became a focal point for mourners after Prince died in April, aged 57. Hundreds of fans brought traffic to a standstill as they gathered outside the club, laying wreaths and singing his songs.
Prince first played there in 1981, and visited throughout his career. His most famous song, Purple Rain, was recorded live at the club and edited down from the original 11-minute performance for release.
He later played warm-up shows for the Parade and Sign O The Times tours at the venue, last visiting for a late-night show in 2007.
"Playing there was always important," said Revolution drummer Bobby Z in an interview shortly before Prince's death. "It became his marquee, and it still is today."
The Revolution first announced plans for a reunion in April.
"We have decided after spending three or four days together now grieving over the loss of Prince that we would like to come out and do some shows," said guitarist Melvoin in a short video. "We want to let you know that we'll be there soon, so we want to let you know now."
The musicians served as Prince's backing band from 1979, although they weren't officially credited as The Revolution until the Purple Rain album.
Prince abruptly terminated their career in 1986 - taking many of the members by surprise. Wendy and Lisa went on to have a moderately successful career as a pop duo, and now work as composers for television, with credits including Heroes, Nurse Jackie and Touch.
Tickets for the reunion concert cost between $65 (Â£50) and $99 (Â£76). Dez Dickerson and Andre Cymone, who played with Prince at the start of his career, will also take part in the show.
"I need this as much as you," wrote bassist Brown Mark on his Facebook page after the show was announced. "I have no closure, I have no peace and the void echoes loud in an empty space deep within.
"Playing my bass is the answer and sharing the music with you is what will heal."

You don't need to go further than the first paragraph in the foreword of the mental health taskforce report to find a bleak assessment of the current state of services.

People with mental health problems have been "stigmatised and marginalised", it says, and services have been "underfunded for decades".
The report, compiled by a panel of NHS and independent experts and due to be published on Monday, does acknowledge that the picture has started to change.
It points out that attitudes are improving and there is now a cross-society consensus on achieving change.
But it says the the transformation of care will take ten years - and the report marks just the beginning of the process.
The 59 recommendations of the report, all of which have been accepted by the NHS England leadership, suggest a determination to shake up all aspects of mental health care.
The aim is to have most of the implementation in place by 2020/21, but even by then the report authors admit that parity of esteem between mental and physical health will not have been achieved, though the process will be some way down the track.
Mental health care 'is ruining lives'
The report does not always make comfortable reading for ministers in the coalition government.
A mental health strategy in 2011, says the report, was widely welcomed at the time but it did not successfully address inadequate provision and worsening outcomes.
There has been "chronic underinvestment in mental health care across the NHS in recent years".
The extent of the financial squeeze and divergence of mental and physical health budgets is underlined by findings from BBC Freedom of Information requests.
These show that the income of mental health trusts in England fell by 2% in 2014/15 after taking account of inflation.
The Health Foundation think tank says that in the same year the income of acute trusts - hospitals dealing mainly with physical health conditions - rose by 2.6% in real terms.
In the current financial year, the BBC research shows mental health trust total income is set to rise just 0.3%.
Some 29 out of 53 trusts which responded expect that by the end of the financial year their budgets will be lower than the previous year.
0.3%
projected rise in the income of England's mental health trusts
29 of 53 trusts in England reported a drop in income
1.4% fall in number of nurses working in psychiatric sectors between 2010-11 and 2014-15
The Department of Health points out that local councils and other organisations also provide mental health services and these are not covered in the BBC research.
But mental health trusts account for at least 80% of spending in this area.
Ministers and the head of NHS England, Simon Stevens, will argue there will be a real annual funding increase of £1bn for mental health by 2020/21.
This will be in addition to the £280m per year already pledged to children and adolescent and perinatal services.
Even so, the £1bn is not "new" - it comes from the £8.4bn extra already awarded to NHS England for 2020/21 by Chancellor George Osborne.
Another problem identified by the report is keeping track of money spent on care of patients with mental illnesses in England.
There is said to be "little or no national data" for how much of the money is used at local level.
Mr Stevens talked of a "black box" with regard to data and has demanded more transparency.
He knows that if light is not shed in this area it will not be possible to assess progress.
The ambitions for the next few years are impressively set out, including the provision of liaison mental health services in all A&E units.
The report is honest in cataloguing the failings of the past.
But it is interesting to note that the year for delivering the targets is 2020/21 which is after the next general election.


Nearly 6,000 patients will be left to "fend for themselves" without a GP when a Brighton surgery closes next February, councillors have warned.

Councillor Gill Mitchell said the closure of Eaton Place Surgery will affect care and called on NHS England to open new premises in the area.
NHS England said Ms Mitchell was wrong and 15 other local surgeries were "ready to welcome patients".
The surgery is due to shut when the practice's two partners retire.
Patients registered at the surgery are worried about having to travel further to find a new GP, according to Ms Mitchell.
"They would like a GP practice in their neighbourhood in Kemptown and that really is not too much to ask", she said.
Local MP Simon Kirby has also written to NHS England to voice concerns about the closure of the surgery, which is based in a district of Brighton.
A spokeswoman for NHS England said it had addressed the points made by Mr Kirby and was working to help those patients affected.
"The only way we can guarantee patients continued access to care after this date is to ask them to re-register with one of the 15 other surgeries located nearest to Eaton Place Surgery," she said.
She added that the 15 surgeries had the capacity to take on all patients affected by the closure and six of them were based within a mile of Eaton Place.
However, Dr Richard Vautrey from the British Medical Association (BMA) warned that the closure will increase pressure on surgeries in the area.
"Those practices will end up picking up more patients and they will not necessarily have the resources to be able to take on more GPs", he said.
Patients registered with Eaton Place Surgery are due to receive a letter from NHS England with further information about registering with a new doctor.


Some 11 million children are at risk from hunger, disease and water shortages in east and southern Africa because of the strengthening El Nino weather phenomenon, the UN children's charity has said.

It has caused the worst drought in more than 30 years in Ethiopia, Unicef said.
Its effects could also be "particularly harsh" in Somalia, amid fears of flooding, it warned.
El Nino is caused by Pacific Ocean warming.
"The weather phenomenon, among the strongest on record, is likely to cause more floods and droughts, fuel Pacific typhoons and cyclones and affect more areas if it continues strengthening as forecast over the coming months," Unicef said in a statement.
It said 8.2 million people in Ethiopia faced food insecurity, while an estimated 350,000 children needed treatment for severe acute malnutrition.
"To make matters worse, the weather phenomenon may also bring flooding to some areas of the country in the coming months," Unicef said.
Ethiopia says it has food surpluses in country which it continues to send to areas affected by the drought.
"The government is working hard to ensure that no-one dies from lack of food in this El Nino year and, contrary to some Western news reports, there will not be famine of any sort, let alone anything remotely like the magnitude of that of 1984," a statement from the Ethiopian embassy in the UK said.
Unicef said severe flooding was also expected in neighbouring Somalia, where more than three million people were in need of aid as the effects of El Nino were already being felt.
In Kenya, the government estimated that 2.5 million children may be affected by floods, landslides, mudslides and diseases linked to the El Nino rains, it said.
In southern Africa, Zimbabwe, Malawi and South Africa have been hit by a drought.
"In Malawi, where almost half the children are already undernourished, Unicef fears the worst drought in almost a decade could cause a further increase in severe acute malnutrition," it said.
In Zimbabwe, the number of people in need of food aid was expected to reach 1.5 million by the time the January-March "lean season" sets in, Unicef said.
In South Africa, livestock has been dying as a result of the drought, and water restrictions have been imposed in the main city, Johannesburg, and other areas, correspondents say.


A man has been arrested by police investigating an alleged attack on a boy near the summit of Snowdon.

Officers appealed for witness after the child, aged nine, was allegedly hit on the head and leg with a walking stick on the mountain in Gwynedd.
North Wales Police said a man in his 30s had been arrested and interviewed.
He has been released on bail.


A settee said to have played a part in Britain's abdication crisis has been sold for £4,200 to the owners of the house where it was a feature in 1931.

The pink velvet settee was owned by the girlfriend of Edward, Prince of Wales, Lady Thelma Furness, who lived at Burrough Court in Melton Mowbray.
She introduced Wallis Simpson to the future king but was later jilted.
The three often sat together on the sofa, now going home, Northamptonshire auctioneer Jonathan Humbert said.
When she heard King Edward Vlll wanted to marry Mrs Simpson and she had been jilted, Lady Furness cut up the settee in a fit of pique, Mr Humbert said.
The king would later abdicate in 1936 to allow him to marry Mrs Simpson.
The restored two-seater settee, which originally had three seats, was sold in heavy bidding at the Silverstone auction rooms on 22 May.
Mr Humbert said the price was reached after a battle between a telephone bidder and the current owners of Burrough Court, the former home of Lady Thelma Furness.
"It's a very fitting end to the amazing story of this settee that it should be going home after 80 or so years.
"I am delighted that the current owners of Burrough Court have secured this little piece if British history."
The pink velvet settee had been 'cut down' three years after the trio had first met sitting on the settee at a house party in 1931.
The same sofa was sold at auction in 2009 for £2,150.


A government booklet linking environmental activism and alternative music to violent extremism has been widely ridiculed by Australians.

Australia's anti-terror minister Michael Keenan launched the Radicalisation Awareness Kit on Monday, urging it be shared in schools.
But the use of a case study of a girl called Karen - who gets into music and student politics before getting involved in criminal protests - has sparked both concern and humour.
The #freeKaren hashtag started trending on Friday, and inspired offshoots #IamKaren and #JeSuisKaren.
The publication, Preventing Violent Extremism and Radicalisation, says young people can become violent because of ideologies such as "environment or economic concerns, or ethnic or separatist causes".
The case study says Karen grew up "in a loving family" but when she went to university "Karen became involved in the alternative music scene, student politics and left-wing activism. In hindsight she thinks this was just 'typical teenage rebellion' that went further than most".
"One afternoon Karen attended an environmental protest with some of her friends. It was exhilarating, fun and she felt like she was doing the 'right thing' for society."
It goes on to describe Karen's involvement in violent environmental protests, and how she felt like "a soldier for the environment", before describing how she eventually became disillusioned and cut ties with the group.
She struggled to "recover" from radical activism, but reconnected with family, found a job "broadly in the environmental field" and developed a "more moderate eco-philosophy".
Environmentalists, teachers and social media users were outraged that the publication lumped together environmental protest and violent extremism.
The International Association for the Study of Popular Music said it "strongly objects to the linking of participation in the alternative music scene to radicalisation of any kind".
"There is no reputable evidence to suggest that listening to certain types of music leads to particular political outcomes for the audience," it said in a statement.
"The idea that young people who like certain types of music are problems waiting to happen needs to be challenged, as it has consequences for them."
The Green Party called on its supporters to tell Prime Minister Malcolm Turnbull "that everyday Australians who care about our incredible natural environment should be congratulated, not demonised".
Minister Michael Keenan said in a statement the first step to preventing young people being radicalised was helping schools to recognise what radicalisation is.
"The potential radicalisation of young Australians to violent extremism, including those in our schools, is something all Australian governments are deeply concerned about," Minister Keenan said earlier in the week.
"It is important that anyone who is in danger of becoming radicalised is put on a different path as early as possible before they harm themselves or others."
The booklet comes amid concerns that Australia is facing an increasing domestic terror threat from people linked to or influenced by militant groups overseas.
Speaking to the media on Wednesday, Australia's new defence minister said the threat from groups like the so-called Islamic State (IS) was "very serious".
"There is absolutely no doubt that there are individuals, leaders in that organisation, who are intent upon disrupting Western democracies," Marise Payne said. "I don't think that the magnitude of the threat should be underestimated."
Australia has cancelled around 125 passports of people believed to be supporting IS and other groups, or seeking to travel to IS-held territory in Iraq or Syria.


Top Ugandan rebel commander Dominic Ongwen has arrived in The Hague to stand trial on war crimes charges.

Mr Ongwen, a feared commander of the Lord's Resistance Army (LRA), was taken into custody at the International Criminal Court (ICC) on arrival.
He was arrested in the Central African Republic (CAR) earlier this month.
His trial will be the first time that a member of the LRA, led by the notorious warlord Joseph Kony, has faced international justice.
Mr Ongwen will appear before a judge on Monday, and will be informed of the charges against him, the ICC said in a statement.
They include four counts of war crimes and three counts of crimes against humanity, including murder and enslavement.
His transfer "brings us one step closer to ending the LRA's reign of terror", ICC chief prosecutor Fatou Bensouda said in a statement.
Uganda agreed that Mr Ongwen should be tried by the ICC despite being a fierce critic of The Hague-based court.
US and African forces had been searching for him since 2011.
He is said to be the deputy to LRA commander Joseph Kony, who is still on the run.
Who is Dominic Ongwen?
Dominic Ongwen - full profile
The ICC has said that Mr Ongwen will be held in a detention centre in the Netherlands until his trial, and will undergo a medical visit.
The UN Security Council and UN Secretary-General Ban Ki-moon both issued statements welcoming Mr Ongwen's transfer from the Central African Republic. Mr Ban called it "a step forward in efforts to bring justice to the thousands of victims of LRA violence".
His transfer from the CAR to The Hague "is a welcome development in the international community's campaign to counter the LRA's dehumanising violence, and to bring perpetrators to justice after more than two decades of the LRA's brutal campaign of torture, rape and murder", US Ambassador to the UN Samantha Power said.
The US is not a signatory to the Rome Statute that set up the ICC, but it facilitated his transfer to the ICC.
It offered a $5m (£3.3m) reward in 2013 for information leading to Mr Ongwen's arrest.
He said that after years of hiding in the forests it was time to face the charges against him.
His extradition comes nearly 10 years after he and four other LRA top commanders were charged. Three have since died and only Mr Kony remains at large.
Mr Ongwen is accused of committing atrocities against civilians in Uganda and in parts of Central African Republic, South Sudan and DR Congo.
The LRA rebellion began more than two decades ago in northern Uganda and its estimated 200-500 fighters - many of them child soldiers - have since terrorised large swathes of central Africa.
