Said Benrahma links up with Aaron Cresswell on the left and he cuts it back to the edge of the box for Manuel Lanzini.

He's free but opts to hit it first time. It lacks power and it's comfortable for Sam Johnstone.

Any goals from this man today?

Said Benrahma's cross drifts straight out for a goal kick. West Ham struggling to get going in attack.

Semi Ajayi has been a threat from set-pieces for West Brom... Is he the target for this corner?

No. Aaron Cresswell gets in the way. It's lifted back in and it comes off Angelo Ogbonna last before Lukasz Fabianski gathers it in.

Dara O'Shea then catches Said Benrahma with a high boot.

Tomas Soucek plays an awkward floating pass into the box but Dara O'Shea coolly chests it back to his keeper.

Said Benrahma was looking to follow up behind.

We've still not really got going... West Ham are content to keep the ball, West Brom are content on defending it.

Matheus Pereira plays a lovely ball through to Kamil Grosicki, who had got the better of Vladimir Coufal.

Grosicki holds it up and tees up Pereira, who had continued his run to the edge of the box, but his strike is way over.

Manuel Lanzini tries to sneak in behind but he's just offside.

The corner comes in from the left and Craig Dawson pulls away at the back post. He's completely unmarked but his header is off target.

That was a chance! Sam Allardyce isn't best pleased with West Brom's marking...

Matheus Pereira and Kamil Grosicki try to link-up on the edge of the West Ham box but Jarrod Bowen reads it.

Pereira is immediately on him, trying to put pressure on the clearance, but he clips Bowen's heels and it's a free-kick to West Ham.

West Brom haven't really touched the ball yet. Tomas Soucek finds Said Benrahma on the left wing but he's got nowhere to go so it comes all the way back.

West Ham have the early possession. It's switched over to Vladimir Coufal on the right before it's pumped up to Michail Antonio.

Off we go!

Predictions?

West Bromwich Albion

West Brom boss Sam Allardyce speaking to BT Sport on return of goalkeeper Sam Johnstone: "Difficult one but Sam Johnstone's record speaks for itself, even before I came everyone talked about how outstanding he's been.

"That's the first game he's missed in about four years and at the moment he is the number one keeper.

"David Button did a good job but at the moment Sam is the best and first-choice keeper."

Loser92: If the Baggies get anything at all at the London stadium tonight it will be a huge boost to their survival hopes. West Ham are in very good form.

TV Talker: Imagine having that kind of deal in place for Robert Snodgrass!

West Ham United

West Ham boss David Moyes speaking to BT Sport: "Momentum in football in general is a good thing - I'll take a win no matter how it comes but we want to keep up the good form if we can.

"We've had moments where we've been up and down but we've got a really good team spirit.

"We've got two or three players showing good form and with the amount of games we have it's an opportunity for Pablo Fornals to come in. We think Michail Antonio can go again we have to be careful with him but we don't have an abundance of centre forwards so we have to just be careful."

Timo Werner has gone 10 Premier League appearances without a goal, and has converted just 9.8% of his shots this season.

That's his lowest figure in a top-flight campaign since 2015-16.

West Brom got a really good win at Wolves on Saturday, which will lift them, but they need to try to build on that this time.

The Baggies got a confidence-boosting draw at Anfield just after Christmas, then shipped nine goals in their next two league games. This is going to be tough for them too, and what happens here will tell us a lot about their character and their chances of getting out of trouble.

West Ham are going well and they don't concede many - Saturday's win over Burnley was their fourth consecutive clean sheet in all competitions.

I know David Moyes well, and the improvements the Hammers have made this season do not surprise me. Give him long enough at a club and he will always sort the squad out. Moyes always looks to get teams right defensively first, then builds from the back. That's what he is doing with West Ham at the moment, and I think they will be too strong for the Baggies.

Prediction: 2-0
