Excellent attack from West Ham ends with Victor Moses bursting into the box - but Tiago Ilori steps across and makes an excellent tackle. Brad Smith is holding his hamstring now. Is that another injury or just cramp?

"It is such a difficult one to call. Seeing the teams before kick-off I thought West Ham, but Liverpool's youngsters have played very well. I think a draw was a fair result. It's there for the taking now."

Liverpool have one sub left, West Ham have made all of theirs.

Will the end-to-end, basketball style game continue in extra time? They are often tepid affairs. Will Daniel Sturridge last?

"You need to try to lift yourself for this last half an hour - it could come down to what the managers are saying now. Bilic is down on his haunches and Klopp is animated too. It has been an excellent game."

We are back under way! Thirty minutes separate us from penalties or a winner.

You can't knock either side for their attacking intent tonight. Great substitutions too - both went for it all the way.

A 94th-minute header from £9m man Jordan Rhodes has seen Middlesbrough grab a point which sends them back to the top of the table!

Money well spent?

Into the wilds of extra time then...

A goal now will surely be a winner. Liverpool attack down the left but Kevin Stewart runs out of gas...

Simon Mignolet duffs a clearance out of play and then does the classic Peter Schmeichel trick of just berating the nearest defender. Love to see that.

Possibly the only time that Schmeichel and Mignolet have been compared...

Call me a luddite but I love watching Andy Carroll play, he just causes havoc. Wins a header at the back post and it drops for James Collins, who thuds in a shot right at Simon Mignolet.

At the other end Daniel Sturridge shoots - over!

Great replay...

Any sign in the stats about who is going to nick this in stoppage-time? Liverpool edge possession and nudge territory. West Ham have cracked more attempts at goal, but more of Liverpool's have hit the target. So nope. Tighter than an ill-fitting pair of jeans...

Divock Origi takes a free-kick quickly, Daniel Sturridge is on the left and cuts it back, it reaches Jordon Ibe and his low drive is pushed away!

There are EIGHT MINUTES added on.

Eight! We could be here until midnight...

Kevin Stewart is now limping after a tackle in midfield. There's been an element of the Royal Rumble about tonight's game as Jurgen Klopp gets himself very worked up about something...

Mark Noble leans back, thinks of Wembley, and cracks in a shot on the bounce from 22 yards which Simon Mignolet has to save. Dimitri Payet is playing in the hole now as Victor Moses goes out wide. Can he win this?

"Big chance. Liverpool gave the ball away to Payet and immediately, despite not having much space, he looks for that forward pass. It was a brilliant ball to Valencia, but that was poor execution."

Ah, that's a lovely pass this time from Dimitri Payet, into the dangerzone for Enner Valencia to attack but he can't keep his header down.

We are closing in on extra time.
