Jarrod Bowen crosses and Tomas Soucek knocks the ball towards the goal with his thigh, but it's saved by QPR keeper Joe Walsh.

Charlie: Dalot's own performance and lack of focus are the main reasons he faces so many direct defensive challenges.

Arsenal

Arsenal manager Mikel Arteta speaking to TNT Sports: "We knew that they were going to give us a game and that is the beauty of this competition, that the margin becomes really close especially when you give them momentum and an a goal. "

"We had to find ways to be dominant and adapt to margins.

"Second half was much better. We did react and we did what we have to do. We are positive apart from the result because we made many changes."

A dangerous ball comes flying into the Blackburn box. Kyle Joseph gets there first with his head but the contact is too thick and it flies over.

West Brom have their first shot in almost 45 minutes of football but Isaac Price's effort from outside the box is saved by Swansea keeper Andy Fisher, who I'm not sure I've mentioned once.

Chris: Absolutely no other acceptable result than a win today for this full strength United team, facing a much weakened Brighton eleven, at home. Let's see if the problem was Amorim or not...

I don't think we can underestimate how important for both theses sides, in different ways, a victory it would be.

From West Ham's point of view they're completely out of sorts with knowing how to win a game of football. They're playing a lesser opponent, we shouldn't forget that.

A really fast start by United but now Brighton have their first corner.

This is a really open game.

Three attempts already - all by United - and two really good saves.

Extra time begins at West Ham.

For both sides, extra-time is not what they want.

It is not job done for either of these sides and we will play another half an hour. In front of how many though, I do not know.

I can see all these white seats popping up, I'm not sure where everyone is going.

So 90 minutes have passed and Blackburn didn't muster a shot on target.

Hull did manage 14 efforts but only one troubled the goalkeeper.

West Ham send on Kyle Walker-Peters and Ollie Scarles for Aaron Wan-Bissaka and Ezra Mayers.

And another great save by Jason Steele!

This time he's at full stretch to deny Bruno Fernandes following a United free-kick.

That took a deflection and Steele had to be alert to keep that out.

West Brom send on Jed Wallace for the injured Harry Whitwell, who only came on the 89th minute.

George Pratt replaces Connor O'Riordan in another change for Blackburn.

Jason Steele doesn't stat many games these days but that was a fine save by the 35-year-old Brighton keeper to keep out Diogo Dalot in the second minute.

It's been all United so far.

Swansea have had 20 shots to West Brom's eight. They deserve to be ahead really.

Oli McBurnie heads across the goal for Regan Slater to nod over the top.

He makes contact first but he gets absolutely flattened at the same time. Should probably be a penalty.

Portsmouth

Portsmouth goalscorer Colby Bishop, speaking to TNT Sports: "When you think about the game and that is the way you want it to start but in the end their class came through.

"We put quite a bit of pressure on them and forced a lot of mistakes and we had a few chances. We gave it a go and the fans were brilliant, they were behind us."

On concentrating in the league: "That's what it was about today, the momentum, obviously it was a great game but the league is more important, we need to get more results."

On his team having players out due to injury: "It's hard a lot of key players are injured, so players have had to step up but that is why you have a squad. Hopefully we will get some of the lads back soon."
