That's that for Bertrand Traore, he has an assist to his name and Willian is on. John Obil Mikel is in for Oscar too.

Dieumerci Mbokani will offer Norwich a direct route, Ryan Bennett is off so it's striker for defender.

Cesc Fabregas has seen more ball than anyone else - 67 touches.

He's been neat and tidy to keep Chelsea ticking over. In all, seven of his 52 passes have found the target.

A lot of the Spaniard's passes have been forward too, not safety first stuff.

It's just not happening for Norwich as Nathan Redmond tries to burst through the away defence but his touch runs for a goal kick.

Alex Neil, head in hands, who can blame him? 

As Russell Martin heads the ball back into the six-yard box Cameron Jerome volleys left footed onto the top of the bar. He has to score, simply has to score.

This to me looks like the moment this contest ended. No flag from the linesman (there should have been), keeper goes down to make Diego Costa's mind up for him.

Probably the best opening of the night for Norwich and Cameron Jerome needs to take these. He peels to the back post smartly and Gary O'Neil swings in a cross. It's a volley - though under pressure - and it's wide. Only eight yards out.

Cesar Azpilicueta pierces the Norwich back four, nice slide-rule pass, too much mustard on it and Diego Costa will not catch that.

Here we go then, what have you got Norwich...

Norwich are unable to field Chelsea loanee Patrick Bamford tonight. The 22-year-old joined Chelsea in 2012 but has never played in a game of meaning.

Perhaps it's refreshing then that the Stamford Bridge club have put more faith in talented 20-year-old Ruben Loftus-Cheek by giving him a new five-year deal.

"The club have done so much for me since I started here as an Under-8," said Loftus-Cheek., external

"Now I want to repay the faith they've shown in me with my performances on the pitch."

He was offside, so we won't be too harsh on Norwich. From here it looks a little too easy.

"You're not fit to referee," comes the cry. 

You can see their point. Chelsea seemed to get a lot of the 50-50 calls and of course, that last one is key as Diego Costa was offside for sure.

"HOORRAAYYYYY". The home fans scream as Oscar is booked for a hack (it really was a hack from behind) on Jonny Howson. 

More angst from the home fans aimed at referee Lee Mason. Wes Hoolahan does not get the free-kick he wants, cue a roar of disapproval. 

Guus Hiddink said before kick-off he hoped his side did not lose focus in this game, with minds potentially on the Champions League. It's been solid from Chelsea and as Norwich raid forward with a threatening look, Gary Cahill is perfectly placed in the area to cut out a cross.

The home fans are incensed and rightly so as replays show Thibaut Courtois picked up a blatant backpass a few moments ago.

There's little room for feeling sorry for yourselves in this game though and Chelsea almost double the lead, Cesc Fabregas crosses a free-kick which almost goes in, a good parry from John Ruddy.

John Ruddy is lightning to leg it from his goal and slide at the feet of Diego Costa on the angle of the area. Costa was an inch from poking the ball past the stopper. Into the book goes Ryan Bennett, foul on Eden Hazard who ran at his man to commit the foul.
