West Brom enjoy a spell of possession as Kieran Gibbs plays it back inside to Romaine Sawyers.

Conor Gallagher then tries to chip it towards Callum Robinson but he skews it slightly and it's comfortable for Lukasz Fabianski in the end.

Romaine Sawyers fancies a piggyback and practically jumps on top of Manuel Lanzini, who had got the better of him.

Declan Rice then tries to drive through the middle before laying it off to Said Benrahma.

Any response from West Brom in the second half?

Team news for the late game will drop in less than 15 minutes. Leicester are hoping Jamie Vardy will be fit to play after he was substituted with a hip problem mid-week. Andreas Christensen could be back for Chelsea.

All three of Vladimir Coufal's Premier League assists have come at the London Stadium.

And nine of Jarrod Bowen's 12 goal involvements for West Ham in the Premier League have come at the London Stadium (five goals, four assists).

West Brom have now conceded 42 Premier League goals this season, at least eight more than any other club (Leeds United follow on 34).

Only three other teams have conceded 42+ goals after 18 fixtures of a PL campaign: Barnsley (47 in 1997/98), Sheffield Wednesday (42 in 1999/2000) and Fulham (42 in 2018/19).

All three of those clubs went on to be relegated in their respective seasons.

Paul Collins: Hard work and organisation can only get you so far. West Brom just have too many players who are not premier league level who will struggle to play in the premier league again if they go down.

A goal which undoes all that good defensive work from West Brom in the first half.

Semi Ajayi tries to pass it back to Kyle Bartley but it's so loose. Luckily, Bartley reacts sharply to slide in and prevent Michail Antonio latching onto it inside the box.

Tomas Soucek knocks it on and Michail Antonio manages to keep it in but he can't get around the full-back.

Doesn't look like we're getting a goal before half time.

Jarrod Bowen works space on the right to get a cross in and it comes over to Said Benrahma. His shot is blocked by Conor Gallagher and West Brom break.

Callum Robinson tries to tees up Matheus Pereira in the middle but the keeper is out sharply.

Aaron Cresswell plays another smart ball down the left. Michail Antonio does really well to hold it up but Declan Rice then gives it away cheaply.

He's annoyed with himself too.

TheTurboBear: Those West Brom shirts are utterly disgusting, and yet somehow still the highlight of this game so far...

Agreed.

Manuel Lanzini takes it but he can't get it over and down quick enough. It ripples the top of the netting but Sam Johnstone looked very calm.

Semi Ajayi catches Michail Antonio on the edge of the West Brom box and there's a free-kick in a decent position.

Aaron Cresswell will fancy it, along with Manuel Lanzini and Declan Rice.

A long diagonal pass opens up space on the left for West Brom. It's slid across the edge of the box and Conor Gallagher leaves it for Callum Robinson. He skies it but that was nice build-up play.

Michail Antonio manages to squeeze it across from the left after skinning Jake Livermore with some nifty feet.

Said Benrahma can't get a shot away but it ricochets kindly for Jarrod Bowen, who almost touches it in from close range but he's offside.

Declan Rice swings a ball in from the right. It doesn't quite drop for Michail Antonio but it's touched on to Tomas Soucek.

He's about to shoot before it's hoofed away. Good defending from West Brom so far!

This is better from West Brom. It's curled in from the left after West Ham lose possession in the middle.

Semi Ajayi is in there but Angelo Ogbonna gets it away before another cross is cleared from Kamil Grosicki.
