Mark Cavendish is 86th overall in the Tour de San Luis in Argentina after finishing the fourth stage 14 minutes behind leader Dani Diaz.
The Manxman earned two second-place finishes in the first three stages but predictably dropped off the pace in the mountainous finish to the fourth of the seven stages.
Image source, @DickieLeeAll around the country, professional footballers have been pitching up for training. And while we don't want to flood Sportsday with weather related tweets (we're not the Met Office), Brentford goalkeeper Richard Lee, external is concerned: "Office is looking crispy today... Is it odd that I consider this 'broken hip weather'? Padded GK bottoms needed."
Brentford visit Norwich in the Championship tomorrow.
After Manchester United manager Louis van Gaal spoke of "twitching my ass" to describe the anxieties of his job, we've been asking for your sporting slang.
Mo:, external 'Lollipop'. Big Ron Atkinson's use of this word to describe a 'stepover' is frankly baffling.
Iain Hepburn:, external Stramash, as famously used by the late great Arthur Montford.
Seun Aladelo:, external Wenger - "I almost signed..."
Harsh, Seun, harsh...
Enjoy seeing people racing on ice, face down, at great speed? Watch the fifth round of the Skeleton World Cup...

The Mail are reporting, external that Manchester City's players will only arrive back home from their training stint in Abu Dhabi at 18:00 GMT - just 21 hours before their FA Cup fourth round meeting with Middlesbrough.

Image source, GuardianThe Guardian have an interesting nugget from Arsene Wenger, who claims he would have signed Angel Di Maria for Arsenal at the age of 17 had the work permit rules in Britain been less strict.
Forget any other claims to be the worst's fiercest derby... the Asian Cup meeting between Iraq and Iran is 3-3 with just a couple of minutes remaining in extra time. We'll keep you posted...

Today's racing at Doncaster has passed an inspection and goes ahead as planned. Earlier Huntingdon was called off because of frost.
Image source, MailMartin Odegaard's slightly bemused-looking fresh face adorns the back page of the Mail after the 16-year-old Norwegian completed his move to Real Madrid. Apparently, when he empties his piggy bank at the end of every month, he'll find a further £40,000 in it.
Not that Sportsday is at all jealous, you understand. We suspect we might not have made it to 18 had we be earning that kind of money at that age...
Anyone for tennis? Because there's plenty more coming up...
Maria Sharapova is facing Zarina Diyas, followed by Rafael Nadal's match with Dudi Sela and you can follow the action here with our colleague Aimee Lewis.

It's safe to say conversations have already been had in the Cambridge United dressing room regarding who wants which Manchester United player's shirt at the end of their FA Cup fourth-round tie on Friday.
But the Express are reporting that the League Two side's players will have to pay to replace their own shirt should they give it away...

"I said to my players I was squeezing my ass but it was the wrong expression, I have twitched my ass on the bench because we were out of balance."
Those were the words of football philosopher Louis van Gaal on Thursday as the Manchester United manager attempted to describe the anxieties of football management. It brought back memories of Sir Alex Ferguson's "squeaky bum time" and got us thinking... what's your favourite sporting phrase?

Now on to the football...
It is a rumour that has rumbled on for a while now, but David De Gea's mooted move from Manchester United to Real Madrid has gathered fresh impetus with Portuguese agent Jorge Mendes refusing to rule out the switch in the Daily Mail., external

Image source, Getty ImagesSpeaking of Murray, he cantered through to a last-16 tie with Grigor Dimitrov after brushing aside Portugal's Joao Sousa 6-1 6-1 7-5.

The Bulgarian 10th seed, meanwhile, needed five sets to get past Marcos Baghdatis earlier in the day.
Image source, Getty ImagesFirst, let's put some meat on the bones of the early morning tennis news...
Four-time Australian Open champion and second seed Federer lost 6-4 7-6 4-6 7-6 (7-5) to 30-year-old Seppi, with the world number 46 recording his first win over the 17-time Grand Slam champion in 11 attempts.
It's also worth noting that Federer was in Murray's quarter of the draw, meaning they were slated to meet in the last eight.
What do you mean you've only just woken up? You've missed all the fun...
In the last hour or so, Roger Federer has been bounced out of the Australian Open by Andreas Seppi while Andy Murray has sauntered into the last 16 in Melbourne. And, just across the Bass Strait in Hobart, England have posted 303-8 in their Tri-Series encounter with Australia.
After that early excitement, there is a danger the next 12 hours might feel a little underwhelming but we're in this together now, so let's make the best of the final Sportsday of the week...
