Watch the quirkier moments from the fourth round of the FA Cup, featuring a birthday present for Jose Mourinho, bouncing supporters and one of the worst corners of all time.

VAR, off-side goals, a missed penalty, five goals and an unbeaten record broken...

This game had it all. But what ultimately cost Liverpool today and what got West Brom over the line and into the fifth round of the FA Cup?

Liverpool have huffed and puffed - and they missed the intricate play of Philippe Coutinho to be honest.

But take nothing away from West Brom - they've battled really hard - and they deserve this win.

Liverpool, seven-time winners, are out of the FA Cup.

West Brom become the first team to beat them at Anfield this season and it's a huge victory for Alan Pardew's side.

What a game that was!

Virgil van Dijk has nearly done it there - but Ben Foster is there again - he's done everything right tonight.

VAN DI-

No. But that was close! The ball just shaves off his head and Ben Foster is scrambling down to his left post.

Phew! Relief for West Brom. What a moment that could have been...

We're into the last minute...

Dave: For all Liverpool's attacking brilliance, if they lose this game, you do have to begin to wonder when Jurgen Klopp will bring a trophy to Anfield. They're not going to win the Champions League with a defence leaking three goals to West Brom...

Mark: What a game - Liverpool have been shocking again!

Pat Nevin is onto something. Remember when Steven Caulker went up front for Liverpool? Throw Virgil van Dijk up top and go for it.

Liverpool have put cross in, after cross in, after cross in. But you've got Virgil can Dijk, Joel Matip and Jordan Henderson waiting on the half-way line - you're going out of the FA Cup - you've got to take a chance.

Now Jonny Evans has pulled up with what looks like a hamstring injury...

Four minutes of stoppage time left to play. Can West Brom cling on? Jay Rodriguez runs it into the corner...

Andrew: Poor set-pieces have really let Liverpool down, I haven’t seen a good delivery all game.

Richard: What a world of difference between Foster and Mignolet.

You can hear the Liverpool fans now, and they're going to keep this up until the end of the game. Liverpool need to go for it, but West Brom have looked really dangerous on the break, especially through Matt Phillips - so they can't just throw Virgil van Dijk up top just yet.

Jake Livermore is struggling for West Brom but Alan Pardew is all out of substitutes.

He's pushing the midfielder forward, to try and get him out of the way of this attacking bombardment from Liverpool.

Ahmed Hegazi was dragging Virgil van Dijk all over the place there - he must have a very short memory. Because if the referee sees that - it'll go straight up to VAR - and it could well have been another penalty.

The Baggies are literally hanging on at the moment.

Liverpool fire a ball in from a corner and it's bouncing around in the six-yard area. There's two or three players trying to poke a foot at it but it's eventually cleared.

The hosts re-build another attack...

But look who has the ball in his hands again...

The outstretched leg of Craig Dawson brings down James Milner, who was away down the left wing.

It's a yellow card from Craig Pawson and Milner will take the free-kick...
