Ooooh.

Granit Xhaka's initial pass is poor but it bounces off Enock Mwepu and comes through to Emile Smith Rowe.

He can shoot but Yves Bissouma comes across to get a crucial block on it.

Joao Pedro tries to spark Watford into life with a mazy dribble but runs into traffic with three Leeds players around him to stop him getting a shot off.

Yan Valery is on for Oriol Romeu. Early change for the Saints. Will it make any difference?

Aleksandar Todorov: 9-0 for a third consecutive season?

Graham Green: Are we finally about to see Southampton’s annual 0-9 match?

Brighton are the ones who are controlling the game now. A cross from the left comes all the way through in the box and as Bukayo Saka tries to break, Yves Bissouma brings him down.

He'll take one for the team and goes in the book.

Watford desperately need a goal before half time. Cucho Hernandez tries to provide it cutting in from the left flank on to his right foot but the radar is well off and the curling effort from the edge of the penalty area doesn't trouble Illan Meslier in the Leeds goal.

Southampton manager Ralph Hasenhuttl has been apoplectic on the touchline in the past few minutes as he shows his side are giving far too much possession away on the halfway line.

He knows this Chelsea side are more than capable of capitalising on those mistakes.

Someone throw Alexandre Lacazette a book or something. He's had six touches in 33 minutes.

Now that his side are one down, he best look a bit lively.

Chelsea aren't giving Southampton time to breathe. Timo Werner is through in the middle with space again but he drags the shot straight at Fraser Forster this time.

Outstanding finish - the chances Brighton have created and chances they've missed, in 102 chances at goal and scored one. You have to be clinical when you get the chance against Arsenal at the Emirates and they were on this occasion.

A rare chance for Southampton but they try to walk it in. It's switched from left to right. There are a few opportunities to shoot but they want to get the ball to Kyle Walker-Peters.

He's closed down quickly and has to squeeze a cross in and it's eventually out for a throw-in.

A half chance for Watford as Leeds can only partially clear a free-kick. It comes to Juraj Kucka, who tries something spectacular with a shot on the turn, only for it to end miles over the top.

The front four for Leeds are really impressive; Raphinha, Rodrigo, Harrison and James. They are on the front foot and they press to set the tone; the centre halves are pushing right up. As soon as Watford win the ball back, Leeds are all over them.

Chelsea fans are having a party in the away stand but it's calmed down a little on the pitch. They are just passing it around with ease in the middle.

Steve Conroy: Chelsea have got to keep Werner. More effort in 10 minutes than Lukaku in 10 games. That's why the fans love him.

Has to score, surely?

Bukayo Saka curls in the free-kick and it's right on the head of Gabriel at the back post. He just needs to hit the target as he's only a few yards out but he thumps it into the side-netting.
