Ben White looks to go on one of those searching runs down the left but he's bundled out the way by Stuart Dallas.

Both managers are about to make some changes...

Leeds are starting to take the game to Brighton more. Marcelo Bielsa has obviously said at half time: 'I want you guys to run even harder and forward more often.'

The pitch is a disgrace. It is not Premier League level. I don't want to blame the pitch, but it isn't helping their cause.

Brighton are comfortable at the moment.

Michail Antonio wins a free kick right on the edge of the Burnley box after flummoxing a Clarets defender with fancy footwork.

Declan Rice then whips a fierce effort over the two-man wall but just over the bar too.

Ezgjan Alioski tees up Raphinha on the left and there's numbers to aim for in the middle.

He has time too but Raphinha's cross ends up flying over everybody and rolls out harmlessly on the far side. What a waste!

Leeds have definitely improved in this half though - Brighton can't seem to get hold of the ball.

Burnley are usually really good in the air but they haven't won their aerial battles today.

They are not winning the first contact. That would be a worry if I was Sean Dyche.

Joel Veltman is beaten on the left and it comes in dangerously towards Patrick Bamford. Dan Burn does well in the end to get his head on it before Robert Sanchez gathers it in.

A dangerous Burnley cross is headed away with Dwight McNeil lurking to nod in at the back post.

West Ham then break quickly and win a corner as Michail Antonio's cross is deflected behind but Jarrod Bowen's delivery is dealt with, albeit not too convincingly.

Leeds have upped the tempo. They have obviously had words. They still need to relax a bit on the ball though because they're rushing everything. They want to get to goal so quickly.

I can't believe they had the water on the pitch at half time though! The pitch is so heavy and boggy but they put the sprinklers on!

Mateusz Klich tries to lift one over the top for Raphinha but it's away by Lewis Dunk. Raphinha then finds Patrick Bamford but when it comes back to Klich, he hoofs it straight out for a goal kick.

I really like Dwight McNeil, he's produced a little injection of impetus for Burnley in the early spells of this second half.

Ben Mee is on the line to block a Michail Antonio header before hacking clear.

West Ham have had an extra day's rest to prepare for this game and they certainly look the fresher of the two sides.

Raphinha pokes it through to Patrick Bamford in the box. He takes a touch but that allows Joel Veltman to come across and make the tackle.

It lands at the feet of Jack Harrison and he smashes it first-time but it flies wide of the far post. Decent effort, decent chance.

I keep thinking Burnley are pulling away quite nicely from trouble but scores today will make them a bit twitchy if they stay the same. Brighton will move above the Clarets, who would be one place above the drop and four clear of Fulham, who have a game in hand.

A result here would be a big boost but it is West Ham who have started this half the stronger.

Leandro Trossard tries to squeeze it through to Neal Maupay but it's cut-out by Liam Cooper.

It comes back in from the left by Brighton but Alexis Mac Allister can't get a shot away, before Maupay skews it wide from the edge of the box.

Jacob Standbridge: Leeds have often struggled against a 3-4-3 defensive shape this season - it allows opponents to close down our wide players with lots of bodies. Good work by Potter to pick up on this. We need to offer a different threat in this half.

Burnley have made a change for the second half with Dwight McNeil on for Johann Gudmundsson.

We're back under way.

Back under way in Leeds. No changes from either manager.

Lord Andrew Dennett: Some of the play between MacAllister and Trossard is sublime. Just imagine how much better it would be on a pitch that wasn't a ploughed field!

Brighton have dropped 12 points in Premier League matches they were leading this season, more than any other side (W2-D3-L2).

Surely not this time?
