They've been a team that's been out of form, had no confidence and they got that first win in the FA Cup just a couple of weeks ago and it's just started to bring them back to the squad that they are capable of being.

That is a terrific goal, Billy Sharp is good in those situations and the celebrations come from enjoying playing with confidence. Looks like they will go on to win this game and they need that.

Rhian Brewster is close again to that first Sheffield United goal, rattling a shot straight at Michael Cooper in the Argyle net.

Norwich with a sniff. Jordan Hugill heads a Przemyslaw Placheta free-kick off target.

A wonderful goal, it is a great pass that splits the defence, then Billy Sharp runs off the shoulder and takes a touch round the keeper. He had a look with composure, but Oliver Norwood's passing ability can thread the ball through the eye of a needle. Great finish, great pass.

The winners of this tie will travel to take on Sheffield United in round five - if the Blades win - and Millwall have started the second half well. Alex Pearce hammers in a shot and it's well saved.

Balcombe is called into action again, this time diving low to save a goalbound shot from Manuel Lanzini. West Ham want that game-sealing third.

Said Benrahma is just warming up to life at West Ham after being arguably the Championship's stand-out player last year. He draws a good save from Rovers keeper Ellery Balcombe with a dipping free-kick.

Back under way at Liberty Stadium. There's a few changes for Nottingham Forest.

Cafu (no, not that Cafu) is on for Fouad Bachirou. Miguel Guerrero is on for Luke Freeman.

And we're back up and running in south London as well.

Which first-half goal was the best?

Back playing at Bramall Lane.

The matches at London Stadium and Oakwell and both back under way. West Ham very much in charge against Donny, while it remains goalless between Barnsley and Norwich.

If you missed it earlier, Southampton knocked out holders Arsenal thanks to an own goal from defender Gabriel.

You decide.

Thumbs up for penalty, thumbs down for no penalty.

And here is that "brilliant finish" from Mr Madine.

Jermaine Beckford

That was a striker's instinct finish. That was brilliant. Great cross in and Gary Madine's positioning, determination and desire to get on the end of that in the manner that he did - brilliant finish.

Michael Brown

It was a solid performance from United, there's been some great runs and good energy to get into good areas. It was a brilliant, well-worked goal, but Argyle had that opportunity for Camara which he put over the bar and they'll be disappointed with that. They've not had much else aside from that.

We'll have team news for this game dropping shortly. Remember it's live on BBC One!

Here's that earlier screamer from Matt Grimes as Swansea go into the half-time break with a comfortable 2-0 lead.
