Wolverhampton Wanderers

Wolves manager Gary O'Neil speaking to ITV: "Really disappointing, up until that point it was a good tie with good atmosphere. Not really sure what happened, the ref advised us to leave the pitch. We don't know exactly what happened, how people behave at football is really important and we need to look at that, make sure everyone is safe. When we came back out the atmosphere had gone, it was really sad to see.

"I couldn't really see what was going on, I know that the West Brom players' families were in that area which is a concern. I really hope everyone's OK, I'm not really sure what stoked it. We got the fixture played without any more trouble happening."

Was it your decision to resume the match? "The safety officers and police were telling us when we could go. We had to take Pedro [Neto] off because we didn't want him starting and stopping, we didn't want players waiting too long. I'm glad we didn't have to come back and play it another time."

What did you do in the break? "Just staying calm, make sure we get some food and fluid on board because it was a late part of the match. It felt like a really important victory."

Pleased with Pedro Neto and Matheus Cunha? "They are both hugely important to us, we are really short as a football club attacking wise in terms of moments, but we do have quality. The amount of quality we have, we are a threat. Delighted with both of them, delighted we got Pedro another good stint."

Can you realistically aim to win the FA Cup? "I don't know about aim, but when we were drawn at Brentford away, our aim was to win the FA Cup. That was Brentford, today was West Brom. We've now got Manchester United and Chelsea coming three days apart. Two tough games and we have to be ready."

There are huge numbers of police outside The Hawthorns and dogs are barking as fans make their way out of the stadium.

Carlos Corberan and Gary O'Neil are due to give their press conferences shortly.

Great effort.

Liverpool forward Darwin Nunez collects the ball on the edge of the Norwich penalty area and instinctively tries to curl the ball into the far corner and is unlucky to see it rebound away off the post.

West Bromwich Albion

West Brom captain Jed Wallace, speaking to ITV: "You focus on the game and then it's kicking off. A lot of the players were distressed because that's where their families sit. They were worried about their children, that's why you could see some of them running over."

On the players: "They're deflated. I think the support we had from the fans was amazing. It was a tight game and we had some chances. It was two goals from two top Premier League players."

On Kyle Bartley walking off with his children: "No-one wants to see that in football. They're two huge clubs with passionate supporters. You hope it keeps a lid on it at times. The game was played in a good spirit on the pitch. You fly into tackles and shake hands after."

On changing room conversations: "We were with the sport science guys trying to keep as warm as possible. We just didn't have that end product today."

On Wolves' quality: "I think it was an even game. It was a 50-50 game. We know the speed and quality they have. We hope we can get promoted this season so we can go again against them next season."

Carlos Alcaraz goes into the book for a foul on Matheus Martins.

Clear frustration from the Saints midfielder.

Liverpool midfielder Ryan Gravenberch zings a cross-field pass from right to left but that sails out of play.

The Norwich fans have something to cheer about.

Joe Rothwell sends a Southampton free-kick into the box.

Taylor Harwood-Bellis is unmarked but he can't keep his header down.

Another Liverpool chance.

Cody Gakpo is left completely unmarked at the back stick but can't control his effort and blazes over from eight yards or so.

Southampton have a chance to score after Che Adams finds Tyler Dibling but his touch is loose and Carlos Alcaraz is unable to react quickly enough to follow it in.

Joe Gomez lets fly with an effort from 20 yards or so that deflects off a Norwich defender and just wide of the visitors' goal.

Jurgen Klopp is up to applaud that and wants more of the same.

David Wagner's team have been guilty of giving the ball away cheaply so far.

'I'm so glad that Jurgen is a red. I'm so glad he delivered what he said,' the Kop are serenading their departing boss..

And here was when the game was suspended because of crowd trouble.

Here was Wolves' opening goal.

Wolves

Wolves captain Max Kilman, speaking to ITV: "It was very tough, we knew before the game it was going to be tough. We performed really well this afternoon."

On crowd trouble: "It's something you need to experience. We adapted really well. We got to together, stayed warm and we finished the game well."

On winning at West Brom: "It felt unbelievable, we haven't won here in so many years. It's very special."

On both goals: "Both really clinical finishes. Credit to Cunha and Neto, they both took their chances."

On FA Cup run: "It's looking good so far but we've got some really tough games coming up in February. We need to make sure we keep going."

What is Joe Lumley doing?

He comes racing out from his goal and is in no man's land.

Watford can't make the most of the opportunity and Lumley breathes a huge sigh of relief.

Norwich lose the ball near their own goal and Liverpool win an early corner.

The Canaries managed to clear that but the hosts have possession back almost immediately.

The fans will want to do their utmost because of what has happened with Jurgen Klopp. He will be a huge miss, not just to this country but to football is he stays away from it.

Jurgen came in and the team has progressed every single year to where they are now - the youth and younger players in this squad is incredible.

The club has got better every single year, the only trophy that eluded him was the Europa League. We all want them to win the Premier League and a Europa League final in Dublin would be the icing on the cake.

Wesley Hoedt plays a teasing ball into the box but no Watford players gamble and it is cleared for a corner.

Jamal Lewis's low shot is easily saved by Joe Lumley.

And away we go.

A reminder of the teams...
