Almost the opener for the hosts.

Little Cesar Azpilicueta is the man leaping highest to meet a corner and it beats Karl Darlow but a Newcastle defender is able to head it off the line.

In the next move, Tammy Abraham heads wide from eight yards out and he should have done better.

Timo Werner has gone 14 league appearances without a goal since scoring against Sheffield United on 7 November.

Can the Germany international fire one in tonight?

Chelsea on the front foot immediately.

The reintegrated Marcos Alonso is found on the left edge of the box and the Spanish wing-back drills a low shot which Karl Darlow gathers low down at the near post.

Arron Newble: Very very worried about Kepa starting tonight. Surely some kind of cruel joke?! Or a belated Valentine's gift from Tuchel to Bruce...

That result leaves West Ham in fourth place, leapfrogging Liverpool and Chelsea, who are up next against Newcastle.

What a job David Moyes is doing!

The Hammers are currently in a Champions League spot. Victory for Chelsea will see West Ham drop to fifth but it's not good news for champions Liverpool, who could find themselves in sixth by the end of the night.

Right, no messing. On to the next one.

That's that then, Graham.

There's a lot of tired legs out there but especially the defence of Sheffield United - couldn't quite close Ryan Fredericks down, there's no one near him. He just drives it into that near post - Aaron Ramsdale has got every right to look at his back four and say why didn't you close the ball down?

West Ham's finishing was the difference and David Moyes' side move up to fourth in the table.

Sheffield United remain rooted to the bottom, 14 points adrift of safety with 14 games left and the greatest of escapes is looking very unlikely now.

And again.

John Lundstram sees the space open up but blazes his shot over from the edge of the box.

How many chances has David McGoldrick had tonight?

The Blades striker decides to take a touch on the edge of the box when the first-time shot would have been the better option and his effort is eventually blocked.

This one is petering out now.

There are still six minutes of additional time to play.

John Lundstram booked for a late challenge, three minutes left.

Hammers fan Amr has tweeted in to say "Can we bring Tevez on now?"

Too soon, Sheffield United fans?

When did we get stretcher carts in the Premier League?

Hold on though.

Play has still not restarted after the Jesse Lingard shot as John Egan has done himself some damage in making the block.

The stretcher is on and the leg brace is out too.
