Mateo Kovacic is on in place of Jorginho, while West Ham send on Said Benrahma.

Awittor Fred: Chelsea still very shaky and unconvincing overall, need that second goal sooner than later. Olivier Giroud’s hold up play could be the key to this.

Paul: Chelsea looking very lightweight.

Great defending! A West Ham cross from the right skids across the edge of the area to Pablo Fornals, who takes a touch and smashes in a left-footed shot. It's definitely going on target until Cesar Azpilicueta makes himself big and blocks it away.

Into the last half hour. Not much to report in this second half to be honest as Thiago Silva tries to head on in the opposition box this time.

Now Angelo Ogbonna heads over after another West Ham free-kick comes in. Good defending from Thiago Silva.

That's as good as a guarantee. Timo Werner now loses the ball on the edge of his own area and Mark Noble's cross is cleared away. Chelsea don't look like they know whether to stick or twist.

A really scrappy start to this second half.

Both sides are struggling to string two or three passes together.

Another man down, Kurt Zouma wiped out at a corner. The physio has covered the most ground on the Opta stats so far.

All a bit flat since the restart. Will David Moyes leave it another 10 minutes or so before making a change?

I think Tammy Abraham had the opportunity to whip the ball in first-time.

It's fired across the six-yard line. Werner is sliding in and there's a collision there. He's caught the keeper.

Lukasz Fabianski is going to be OK. West Ham are covered of course - they've got two keepers on the bench tonight!

Tammy Abraham now fires in a decent cross from the right and Timo Werner slides in - misses the ball and collects a chunk of Lukasz Fabianski instead.

Half a chance for West Ham!

Jarrod Bowen does really well to hold off his man on the right and sweep a crossfield pass to find Aaron Cresswell.

His cross is a good one, Seb Haller gets up to meet it but under pressure he can only squirt a header well wide. Bit of a 50p head job.

A Jorginho mistake almost lets West Ham in but he recovers well to sweep it up.

No more changes - Jorginho's knee must be sound.

Here we go then.

Chelsea are unbeaten in their last 83 Premier League home matches in which they had the lead at half-time (W68-D15-L0).

The last time the Blues lost at Stamford Bridge after leading at the break was against Arsenal on 29 October 2011 (5-3).

I don't know where Nuno stands with a fine making comments like that. He hasn't said Lee Mason is biased or corrupt - just rubbish.

In his opinion.
