We go again. Martin Odegaard hasn't been hooked off at half-time, he's fit enough to continue.

The Manchester United players are already out. They've been decent, defensively at least, so far today.

Eddie Howe does NOT want to entertain the idea of extra time. He's sent on Bruno Guimaraes and Anthony Gordon at the break for Joelinton and Harvey Barnes.

A half-time change at Portman Road for the hosts - Ben Johnson replaces Wes Burns.

We are back under way.

We're back under way at Selhurst Park.

No goals so far at the Emirates - but the ball has been in the net...

Hopefully, Gabriel Jesus will be back soon but it does not look good.

Raheem Sterling has not played for a long period of time and it is hard for him to get up to speed.

The Arsenal fans want signings, it's a big ask [to sign someone], especially in January.

Martin Odegaard is the one you are looking at to unlock the door.

He is the one who is trying to open up the Manchester United defence but the movement in front of him is just too slow.

People need to take more responsibility for Arsenal.

Arsenal aren't great at creating chances at the moment in the forward line, they are relying on set pieces.

Kalvin Phillips has had a rough couple of years, but this is a lovely goal.

It's his first competitive strike since scoring a penalty for Manchester City against Crvena Zvezda in the Champions League in December 2023.

Arsenal are at home, the onus is on them to have possession and break Manchester United down.

Arsenal need to do more. They're just a little bit flat.

Sutton's prediction: 3-2 after extra time

The fan at St Mary's last weekend who said Southampton would lose 5-0 to Brentford should really replace me and do these predictions.

This tie is a lot harder to call, though. You could call it the Russell Martin derby, because he managed both teams, but I am not sure either side play like they did when he was in charge.

Saints boss Ivan Juric has got to pick a strong side after what happened against the Bees, and his aim must be to find a team that starts to find some rhythm again.

I do think Southampton will edge this, because they have to, but what a miserable existence it has been for their fans this season. Maybe the FA Cup will give them something to cheer about?

We have had two absolutely brilliant goals in this game. It has really lit this game up and it does make you think - even though Bromley were under a lot of pressure in the last 10/15 minutes - Newcastle haven't had that many chances. You just feel that more space will develop as the game goes on.

We have had one upset today.

Here's how League Two side Doncaster beat Championship strugglers Hull City.

If ever a team needed a win this weekened it's Southampton and new manager Ivan Juric has named a pretty strong side, with a rare chance to impress for Kamaldeen Sulemana.

Swansea leave veteran Joe Allen on the bench and will be hoping to end a run of seven FA Cup defeats in a row against Premier League sides.

Southampton: Ramsdale, Walker-Peters, Bednarek, Harwood-Bellis, Manning, Aribo, Ugochukwu, Bree, Dibling, Fernandes, Sulemana

Swansea: McLaughlin, Tymon, Naughton, Christie, Key, Peart-Harris, Grimes, Franco, Ji-Sung, Bianchini, Ronald

Tamworth boss Andy Peaks, speaking to ITV: "Be disappointed because we were that close to causing a massive upset, but equally be massively proud.

"Everyone put a shift in and when you look at the team we were up against, it was unbelievable from our boys - I am so proud of them.

"We had chances, the keeper made saves but what was brilliant is we were in the game right till the end.

"We knew it was going to be tough. I wanted people to see what we were about, and I think we have done that.

"I wanted to come here and talk to you guys and be proud of what I have seen - I am immensely proud.

"To get a home draw was better. The chance we had to level it was them coming here. They have been so respectful and to bring a team like that says a lot.

"I cannot knock them."

Spurs boss Ange Postecoglou, speaking to ITV: "It was a challenging game as we expected it to be.

"They made it hard for us, with the surface it was about us staying clam and being persistent in our football.

"In the end, we got the job done."

On message going into extra time: "Stay clam and persistent. We knew we would finish strong and you could see they were tiring a bit.

"It's a game of football you go into it with trepidation and knowing you can slip up with the challenges.

"Most parts the boys kept their heads. I thought they stayed clam and persisted and got through.

"We are through to the next round and that was the objective for today.

"Tamworth did really well and should be proud of their efforts. For us, we move on."
