Kepa is back! Sort of.

This tie is really opening up.

West Brom's response from Allan Saint-Maximin hitting the post is immediate as Charlie Austin lets fly from the edge of the penalty area and forces a fine save from Karl Darlow.

Decent game this.

Good ball from Mason Mount to Willian, who is on one tonight, he puts in a low cross which is heading nicely for Mount but VVD sticks out a leg and clears.

'Getting away with it' for 50-odd games...

Allan Saint-Maximin clatters the West Brom post from 25 yards out after a lovely lay off from Joelinton.

Lovely effort. The post is still rocking from that. Newcastle are getting closer.

Anonymous: Liverpool again contributing to their own downfall tonight, as at Watford. They were getting away with it during the season, has the luck finally run out...?

Free header. Boom.

And Kovacic can't carry on. Welcome to the game Mason Mount.

Chelsea 1-0 Liverpool

Mateo Kovacic is down in a heap, not sure what happened there but he's in a bit of bother here.

Frank pinned his hopes on Tammy Abraham but since Abraham's injury he's had to pick either Giroud or Batshuayi and neither have lit the place up. But Chelsea can play off Giroud much more than Batshuayi.

Newcastle do look a little bit sharper and seem to be moving it quicker than West Brom.

Adrian, look away now.

Joelinton looks good against Championship opponents!

He gets on the end of a corner to tee-up a glorious chance for Sean Longstaff but he hacks it high and wide.

That's going to end up in Wolverhampton!

Roberto Firmino and Mo Salah are both on the bench for Liverpool tonight and are having their names chanted from the away end.

A mate of mine has just said this is the most entertaining game he's seen in the FA Cup since Chesterfield v Boro in 97. That might be a bit of a stretch but this is a good one!

That's more like it from Joelinton!

The Brazilian cuts in from the left and goes past two West Brom players before forcing Jonathan Bond into a smart save.

Joelinton is down and looks to have hurt his shoulder after hitting the turf but is soon back on his feet and able to continue.

Good again from Chelsea, Pedro crosses nicely from the left and Ross Barkley just missed the header. Cleared out, ricochets about and Mateo Kovacic puts it in the corner but play had long since stopped for offside.

What a player Mane is. He can create things out of nothing. He's so fast, so powerful, he just bullied Rudiger there and was quick to get his shot away.

He's so difficult to defend against.

Excellent from Willian again, shoddy from Fabinho again, he's on half speed tonight. Willian gets past his compatriot and flashes in a low cross which Neco Williams does well to clear at the back post.

It's a game of chess at the minute but no one wants to take the initiative. The team that calms it down and strings four or five passes together will take charge.
