A tame London derby comes to a close, then. Tottenham miss the chance to go fourth and Chelsea climb to 14th. Probably a good idea to skip the highlights of this one later on.
FULL TIME: Tottenham Hotspur 0-0 Chelsea
There is a Chelsea change but it won't be Costa entering the fray; Kenedy comes onto replace Willian.
Oscar nutmegs a Tottenham player for the third time today and is blocked off the ball in the process, winning a free kick. Willian whips it into the six yard area but Tottenham can clear easily. There are just three minutes of the 90 left.
Diego Costa has been warming up for the past 10 minutes or so, but it haasn't been the most intense session. Is Mourinho considering bringing him on or his Costa just feeling the cold a bit on a chilly afternoon in north London?
There have been so many overhit shots this afternoon. Pedro is the latest to go for a conversion, skying his effort woefully from 25 yards out.
First change for Tottenham as Son comes off for Clinton N'Jie.
Chelsea denied! Fabregas floats a wonderful pass over to the far post where Hazard has slipped clear of Walker. He drills a first time effort on goal but Lloris somehow gets in time quickly enough to bat the ball away. Tremendous save.
Matic is left in a heap after being caught by the elbow of Lamela while jumping for a header. There's no malice in it, but the Serbian will need some treatment.
Neat stuff from Spurs and Son in particular, who cuts inside from the left befre laying a one two off to Lamela. The Argentine scoops a wonderful return pass over the top for the South Korean, but he can't quite get the right contact to sufficently trouble Begovic.
Matic becomes the first Chelsea player in the book after a cynical one to take down Eriksen who was threatening to break.
A moment of confusion between Eriksen, Alderweireld and Vertonghen almost allows Hazard to step in with nothing but space in front of him but Vertonghen just about manages to hook the ball out of his path.
Son slips a ball down the inside right channel for Mason to run onto but as he cuts it inside Ivanovic, he jarrs his ankle and is left in some pain. The stretcher is out, but Mason is able to hobble off and it looks Erik Lamela will come onto replace him.
Jan Vertonghen joins Walker, Rose and Kane in the referee's book after a rash one from behind on compatriot Hazard.
And we are back underway for the second half.
HALF TIME: Totenham 0-0 Chelsea
Walker goes in late on Azpilicueta down the left and is shown a deserved yellow. Willian whips in the resulting free kick but whoever gets his head on it, Ivanovic I think, is ruled offside. That will be that for the first half.
Another poor effort on goal from a Tottenham player, this time from Kane. Vertonghen ventures forward down the inside left and slips the ball into the England international who slams his shot well over the bar.
Oscar shows up Mason with a clever nutmeg on the edge of the box. Alderweireld gets across to put the Brazilian under pressure who, from a very tight angle, opts to have a shot on goal and fires into the side netting.
Harry Kane is shown a yellow card after a miscued challenge on Willian.
Dier does well to hold the ball up and turn, feeding it into Son. From 30 yards out, the South Korean takes aim and shoots, but it's a fairly woeful effort that floats well over the bar.
Spurs deal with the resulting free kick with ease and clear. Moments later Fabregas gets a long range pass completely wrong, smashing it comfortably out of play.
Danny Rose is shown a yellow card for the dumbest challenge you'll see all day. Hazard is going nowhere in the corner, he doesn't even have control of the ball, but Rose feels a sliding challenge from behind is needed.
Brilliant stuff from Dembele, who receives the ball in from the right and easily slips past Fabregas before arrowing an effort for the bottom corner. It's a fair bit out, however, and Begovic is able to get down and save in time.
Begovic denies Son! Kane pulls out onto the right and plays a neat one two with Walker before swinging in a fantastic cross that Son plants on goal, but doesn't get any real direction in it.
