Getting under way in the first four games of the night. Where's the first goal coming from?

Ben Rogers: This Brighton line-up confirms it - January fire-sale to bring Diego Costa in.

Southampton were a bit subdued in their draw with Fulham, but they were missing some key men in Oriol Romeu, Jannik Vestergaard and Danny Ings.

I was a little bit surprised by the West Ham team that David Moyes put out against Brighton, and they didn't start well either.

The Hammers still got something out of that game, but I think they will find things a lot harder against Saints.

Prediction :2-0

If you watch Leeds United as a neutral, you love it. If you watch Leeds as a fan, you're constantly on edge every single game because it is such an exciting, open and expansive type of football that Leeds play.

But...on the other side of it, as we saw against Manchester United and Crystal Palace, if you work the system well, you could end up winning by a good few goals.

Fingers crossed today that Leeds have learnt their lessons and come out victorious.

Southampton captain James Ward-Prowse is the outfield player on the longest run of consecutive Premier League matches, with today his 73rd successive appearance in the competition for Saints.

That's a run which now extends beyond the two-year mark, since he was an unused substitute in a 2-1 home defeat against tonight's opponents West Ham, on 27 December 2018.

He overtakes Dwight McNeil, who misses Burnley's game tonight.

Sheffield United

More from Sheffield United boss Chris Wilder: “We are looking for that big result and big performance. People talk about last season and we had a perfect storm.

“It is the opposite of that this year but we are streetfighters and we are in there fighting as seen in all the performances this season bar maybe one.

"We are not at all happy with the situation and we feel that we should be doing better in terms of points on the board.”

Leeds United

Leeds United head coach Marcelo Bielsa, speaking to Amazon Prime: "We would like to repeat the result from the Burnley game and the performance in the first half."

On the threat of Kalvin Phillips and Mateusz Klich picking up their fifth bookings of the season: "If it happens it will worry me after the game, now all efforts focused on winning against West Brom."

West Bromwich Albion

West Brom manager Sam Allardyce, speaking to Amazon Prime before being forced into that late change: "It was a difficult choice because we saw yesterday how many managers changed the team and put in fresh legs.

"But for me there were two things, trying to get consistency and to be fair to the team to try and get another result like they did at Anfield, hopefully that will work.

"If fatigue kicks in we will have to make the right changes at the right time. But we go with the same team and try to get the win."

On tonight's opponents Leeds: "They are all out attack, sometimes they leave the back door open and we have to try and exploit that. That gives us some hope and if we use the ball correctly we can threaten them. But we have to be good defensively as well.

"If we can capitalise on their record at defending set-pieces, as we did from a corner against Liverpool, whichever way we score a goal is very important to us."

Sho: Brighton chucking in the towel before the game's even started with that lineup. Considering their recent record against Arsenal to have Welbeck, Maupay, Connolly, Trossard and March all on the bench is ridiculous.

Sheffield United

Sheffield United manager Chris Wilder on positive coronavirus tests at the club: “It’s impacted us because we have a couple of players missing through illness and we had a player that had to go and get tested this morning.

"We have a couple of injuries as well so it is not ideal but we have to work with what we have got.

“We just notified the relevant authorities that we have had a situation at the club but I want to play, that’s how it is. We were not looking to get anything canned.

“We did the right thing in terms of our response with the Premier League in notifying them and told them the situation regarding the players that are ill and I think four or five backroom staff have tested positive as well. It’s not an ideal situation but we are not in a club of one.

"It is picking up and running through football clubs and I don’t think we will be the first to be affected by it.”

Arsenal have not won a league match at Brighton since a 1-0 triumph in April 1981.

The Gunners' Boxing Day victory against Chelsea ended their seven-match winless league run.

Brighton, meanwhile, have won just once in 13 league fixtures, drawing seven and losing on five occasions.

Leeds United

Leeds United midfielder Mateusz Klich: "It is very important to keep the winning momentum. The teams going to be around us we have to win against them and West Brom are going to be there. We have to beat them today.

"I don't mind if we score early goals because it is always easier, but we have to be focused for 90 minutes. The Burnley game was very hectic and stressful, but we couldn't score a second or third goal to kill the game. West Brom will be difficult to beat, it will be a tough game."

Leeds have won two of their last three league matches.

They have scored eight goals in those three fixtures, as many as their previous seven top-flight matches.

West Brom have had just six shots in their two league fixtures under Sam Allardyce. Leeds have had 28 shots in the same period.

West Brom surprised everyone by getting a point at Anfield, but they deserved it.

This is another test for the Baggies defence, because you just know that Leeds will come at them in waves.

They were well organised and showed the spirit that Sam Allardyce will demand from them in that draw with Liverpool, but do they have the quality they need to win games like this? I am not convinced.

Prediction: 0-2
