Michail Antonio has just scored a header and tries to get another one, but instead heads across goal and not at it, with none of his team-mates anywhere near him.

Antonio has put himself about a bit tonight.

He's been isolated at times, which isn't great against League One opposition, and you expect players to get in and around him.

David Moyes punches the air, he's delighted.

Essentially it's game over. It's a long way back from here for Derby.

It just sat up beautifully for Michail Antonio and he couldn't miss.

Paul Warne will be bitterly disappointed. West Ham haven't been at their best but they are 2-0 up.

Michail Antonio used his BBC Sounds podcast to say last week that he might leave West Ham this transfer window.

David Moyes was quick to quash that suggestion.

The reason is pretty obvious. With Gianluca Scamacca and new signing Danny Ings injured, Antonio is the Hammers boss' only fit striker.

Derby's Jason Knight gets the ball on his right foot on the edge of the penalty area and goes for the bottom corner but visiting goalkeeper Alphonse Areola can watch the ball dribble well wide.

Derby's challenge will be to start creating but if they are still in the game with 15 or 20 minutes to go then they'll have to throw everything at West Ham.

You expect more from West Ham. It hasn't really clicked for them.

I suspect David Moyes will have had harsh words with his players at half time.

And we're back in action for the second half. No changes from either boss at the break.

Can Derby County turn this one around? They are one of four League One sides left in the FA Cup with Sheffield Wednesday facing Fleetwood in a replay, while Ipswich Town also have a chance to progress, but need to win an away replay at Championship Burnley next week.

If West Ham see this through it will set up a fifth round away tie at Manchester United which, funny enough, would be the third successive season where those two sides have met in a cup at Old Trafford.

Scott McTominay scored an extra-time winner in a 1-0 victory for Manchester United in the fifth round of the FA Cup two seasons ago, before West Ham got a bit of revenge the next campaign with a 1-0 win in the north west in the third round of the Carabao Cup.

If it is Man Utd v West Ham, don't expect many goals as all of their last five games at Old Trafford have only seen the one goal in each of them.

West Ham haven't been at their best.

The first half has been about one moment when Bowen had an easy opportunity from four yards.

Other than that, they haven't been fluent in the final third, and neither have Derby but they have been industrious.

Paul Warne will feel there is more to come from his side and, at 1-0, they are still in this tie.

Jarrod Bowen's 10th-minute goal gives Premier League West Ham the advantage at the break, but the League One outfit have battled well, and are having some success down the flanks.

However, Alphonse Areola in the away goal has not been tested yet and Paul Warne will be hoping his side can change that after the break.

David Moyes doesn't look happy and I get it. They haven't been slick enough or quick enough with possession.

Nathaniel Mendez-Laing and Tom Barkhuizen are causing problems for Derby down the right and left flanks respectively.

Mendez-Laing with a step over and burst of pace sees him sprint past Emerson but Angelo Ogbonna is well placed in the six-yard box to launch a no-nonsense clearance.

There was a moment a few minutes ago when Tomas Soucek get possession about 15 yards inside the Derby half. not far from the right touchline.

He looked up and saw Emerson Palmeiri on the other side of the pitch outside the side of the Derby box.

The pass must have been 60 yards. Under no pressure, it was delivered perfectly. Emerson, with a bit of space to work with, killed it dead.

Nothing came of the attack but it could have done. The speed and accuracy was amazing but it happens so often in the English top flight, it is almost routine.

We used to see Bowen make runs in behind a lot last season. There have been times when West Ham have had it in midfield tonight and they haven't looked for him.
