Kepa is the only player to play every single minute under Potter since his arrival as head coach and he retains his place between the posts this afternoon.

Brighton vs Chelsea injury updates

Chelsea will be without long-term absentees N'Golo Kante, Reece James and Wesley Fofana.

Kalidou Koulibaly is also expected to miss the match, with Graham Potter saying before that game: ‘Koulibaly has an outside chance for Wednesday but not tomorrow,' reported Potter.

However, there was better news on Mateo Kovacic, who was withdrawn early during our midweek win against Red Bull Salzburg. ‘Mateo has no problem with his calf, it was more fatigue,' reported Potter.

Brighton are not expecting Jakub Moder to return until next year. However, they are hopeful that Adam Lallana and Joel Veltman will be available after going off injured in their last match.

Brighton vs Chelsea press conference

Potter used his customary pre-match media briefing to offer his support to Raheem Sterling, who is without a Premier League goal since August despite netting three in his first five for the club.

‘No you shouldn’t be concerned,’ Potter replied when pressed on Sterling’s form heading into the World Cup.

‘His quality speaks for itself. Sometimes the team doesn’t function as well and the team suffers. It is better to think about how we can attack better and create more chances,’ he added.
