By no means a like-for-like swap as Victor Moses comes on for Joey O'Brien.

Decent effort from Christian Benteke, he gets the free-kick over the wall and very much on target but Darren Randolph glides across to push it away. Anyone's game, now Joey O'Brien is down injured...

That was a glimpse of what he can do, Daniel Sturridge nutmegging Joey O'Brien and winning a free-kick. Lovely. 

Stephen: Hope Sturridge and Carroll don't tackle each other. They'll be out injured for years

This has been a very decent FA Cup replay. I've enjoyed watching Liverpool's second-string more than their first-choice XI in recent months. Divock Origi and Daniel Sturridge then play a neat one-two but Darren Randolph is alert to sweep up on his line and cut it out.

Extra time is on the horizon.

Here he is, Andy Carroll on for Cheikhou Kouyate, who is up and walking now. I think he wants to carry on actually but he's not being allowed to.

Liverpool have Lucas at centre-back remember. Must be a good six or seven inches difference in height between those two...

Andy Carroll is being readied. Just what Lucas wanted to see...

"The change of system has not helped Liverpool, you would think with Origi and Sturridge coming on it would give them more impetus. But they have not found a footing. I think that's because they've taken Coutinho off - he was such an influence going forward. Liverpool have lost their way a little."

West Ham 1-1 Liverpool

The injuries are mounting up now as West Ham midfielder Cheikhou Kouyate appears to be knocked out cold. He hits the deck hard after a clash of heads and Kouyate is in trouble. He is very quickly surrounded by medical staff though and after a concerning 20 seconds or so he does move and begins to sit up. 

The referee overrules the linesman after he crazily gives a corner, it's all bubbling away now. Good game - the winners go to Blackburn remember in the last 16...

"Whether Enner Valencia would have got onto the cross or not is irrelevant. It was a brilliant ball played into a dangerous area by Antonio and Valencia was clearly pulled back. It was a definite penalty and a bad decision by referee Roger East."

I don't think West Ham sub James Collins has touched the ball yet but he appears to be injured. He's holding the bottom of his shinpad and limping uneasily away.

Slaven! Get your kit on!

Michail Antonio's first touch is superb to take him past Brad Smith and he teases in a low cross, Enner Valencia is there but he goes down! Oh and Tiago Ilori tugged him down too. He had him by the wrist. Liverpool have got away with one there!

Daniel Sturridge is having to change his boots already, he's not played all winter I suppose. Not a day for moulds Dan...

James Collins is on, replacing the hobbling Winston Reid. Mr Dependable.

West Ham 1-1 Liverpool

Michail Antonio hits in a teasing cross/shot which forces Simon Mignolet into a tricky push over the bar. West Ham looking dangerous but if Liverpool get the ball to their front three they'll fancy their chances.

And now Liverpool do break, Daniel Sturridge is the man over but he's offside! Winston Reid's hamstring pinged on the way back. Game over...

The cheek of it from Philippe Coutinho...

Daniel Sturridge is on for his first appearance in two months. He has only played six times all season - and scored four goals...

"I think it is a penalty. Mignolet misjudges the cross, Kouyate gets across him and Mignolet pushes him away. Actually...I'm not sure. I thought it was initially but having seen the replay I didn't think there was too much contact. None of the West Ham players appealed either.

"This is going to be so attacking now - with all the attacking bodies on the pitch Liverpool are only going to go forward."

Big change for Liverpool as Daniel Sturridge and Divock Origi both come on. Off come Philippe Coutinho and Joao Teixeira...
