23' It's been quite a free-flowing game so far, albeit one without much incident. James darts in behind Burn to reach Ziyech's nicely weighted pass. Burn dives in to win the ball and knock it off James for a goal-kick.
22' James crosses into a decent area. Unfortunately for him there's no one in Chelsea blue to get onto the end of it.
20' Sanchez makes a point-blank save from Ziyech as Webster makes a mistake in a dangerous area again. Zouma unleashes a rocket from distance but Sanchez is back in place to catch it.
18' Jorginho tries to pick out James down the right but James is outmuscled by the massive Burn. Brighton's recent defensive record shows they're not going to be an easy side for Chelsea to break down.
16' Brighton are very tidy on the ball. It's admirable. Webster gives it away in his own half though and Pulisic shoots on the swivel from just outside the box. It's off-target.
15' You wonder whether all the controversy of the last few days has had an impact on the Chelsea players. They can't have had the smoothest run-up to this game.
14' Brighton earn a free-kick down their left. Gross looks to slide Welbeck in down the channel rather than loft it into the box. It's a clever idea if unsuccessful on this occasion.
12' Bissouma hands the ball straight to Havertz with a sloppy pass back. Chelsea race forward and Alonso can't quite reach a cross intended for him at the far post.
10' Havertz is almost in a position to poke Chelsea into the lead as he latches onto a pass over the top. Sanchez races out of his goal and is unable to catch it. Luckily for the Brighton keeper a teammate is there to mop up.
8' Burn clatters a cross against James and earns a throw-in for Brighton down their left. Brighton keep possession there for a while before Trossard gives away a soft free-kick.
6' Pulisic skips over a challenge in the centre of midfield but Trossard gets back to steal the ball. It's all fairly even in these early stages.
4' Chelsea are beginning to get comfortable on the ball, popping it around without a care in the world. Tuchel's side have looked rock-solid of late.
2' Brighton get the first attack of the game as Burn hangs the ball up into the box from the left. Kepa, continuing as Chelsea's starting goalkeeper for now, claims it easily.
1' The players are finally out at Stamford Bridge. Chelsea are in their royal blue home kit. Brighton are in their yellow and white away colours. The referee Stuart Attwell blows his whistle and Brighton get this game underway!
Kick-off for this game has been pushed back by 15 minutes. That's due to Super League-related protests outside Stamford Bridge delaying the players from getting into the ground.
Chelsea will be confident of getting an important win here which will boost their top four hopes. The Blues are unbeaten in their last 14 games against Brighton, a record dating back to 1933. Brighton have lost all six of their visits here to Stamford Bridge, failing to score in all of them, while Chelsea have never gone behind in these sides' seven Premier League meetings. Will recent events motivate Brighton though?
Chelsea boss Thomas Tuchel continues with his squad rotation policy. There are four changes to the team that beat Manchester City 1-0 in the FA Cup semi-final as Christensen, Zouma, Alonso and Pulisic start. Mendy returns to make the bench. There are three changes to Brighton's starting 11 from that draw with Everton last week.
SUBS: Jose Izquierdo, Steven Alzate, Andi Zeqiri, Davy Propper, Neal Maupay, Jakub Moder, Jason Steele, Adam Lallana, Alireza Jahanbakhsh.
BRIGHTON AND HOVE ALBION (3-4-3): Robert Sanchez; Ben White, Lewis Dunk (c), Adam Webster; Joel Veltman, Pascal Gross, Yves Bissouma, Dan Burn; Alexis Mac Allister, Danny Welbeck, Leandro Trossard.
SUBS: Billy Gilmour, Timo Werner, Edouard Mendy, N'Golo Kante, Cesar Azpilicueta, Olivier Giroud, Ben Chilwell, Callum Hudson-Odoi, Emerson.
CHELSEA (3-4-3): Kepa Arrizabalaga; Kurt Zouma, Andreas Christensen, Antonio Rudiger; Reece James, Jorginho (c), Mason Mount, Marcos Alonso; Hakim Ziyech, Kai Havertz, Christian Pulisic.
Brighton enter this game 16th in the Premier League table, probably but not entirely safe from relegation. Graham Potter's men continue to look defensively solid, securing their 10th clean sheet of the season last time out with a 0-0 draw against Everton. One more win for them would probably be enough to allow them to start planning for their next top-flight campaign.
Fresh from reaching the FA Cup final last week, Chelsea enter this game distracted by their involvement with - and apparent withdrawal from - the mooted Super League as they look to avenge their shock 5-2 loss to West Brom in their last Premier League home game. No doubt some football fans would want that scoreline to be repeated again here.
