How have Swansea not scored there? Malick Yalcouye is free inside the box and slots the ball past the keeper. Everyone is expecting it to roll in but it hits the post and comes out.

Feel for the 5,000 in the ground today. It's been far from a thriller and it's freezing.

Proper dedication.

This is a cagey game now. Neither side wants to make that one mistake.

Brilliant pass. He should score, it's as simple as that.

Dalot's first touch - it's slightly heavy - is probably what allows Steele to come out.

That said, it's an excellent save.

Two chances for Diogo Dalot in the opening two and a half minutes.

And what a ball by Matheus Cunha to present him with his first.

A highly encouraging start by Darren Fletcher's side.

West Brom's Chris Mepham is booked for a foul.

Extra time is under way in Hull.

Extra time needed here.

A huge chance for United!

A simple ball over the top and suddenly Diogo Dalot is clean through but Jason Steele makes the save.

Then another chance for Dalot moments later but he fires over.

West Ham striker Valentín Castellanos desperately tries to throw himself at a long ball but can't turn it goalwards.

A quiet start. Lots of possession by Manchester United in the opening exchanges but they're not getting very far.

QPR bring on Kieran Morgan for Rayan Kolli.

Three minutes into extra time and West Brom still haven't had a shot since before the 60th minute.

Will interim boss Darren Fletcher lead Manchester United into the fourth round?

Nicky Butt complained on his podcast recently Manchester United had threatened to take his season tickets away for non-use.

Butt personally isn't using them today. He is in the directors box with fellow Class of 92 member Paul Scholes, both of them sat near their former boss Sir Alex Ferguson.

It's amazing to think of the players involved today, Brighton skipper Danny Welbeck was the only one to play under Ferguson.

Billy: If West Ham lose this game is there any hope for Nuno?

Stuart: West Ham fan since 1969. Still can't see us winning this game...

Arsenal

Arsenal midfielder Christian Norgaard, speaking to TNT Sports: "In the beginning they were than us and could have gone up twice but then when got the momentum. In the second half we could have made more than four goals.

"The start wasn't good enough. I think we were as prepared as we could have been. In this weather and conditions it is never easy in the cup games and credit to Portsmouth."

On how set pieces helped Arsenal win the game: "It's important in our games but it's important in any team. Of course we emphasise it a lot but it's a really important part of our game and it's an important weapon of ours. We will keep developing an using it when we need it."

On the win today: "I think it shows that we are heading in the right direction as a team."

Into injury time here now.

To extra time we go.
