Adam Wharton is back in the Crystal Palace starting line-up but captain Marc Guehi is not in the squad.

As well as Wharton, Daichi Kamada also comes in and Jaydee Canvot replaces Guehi. Will Hughes and Yeremy Pino drop to the bench.
Crystal Palace XI: Henderson, Richards, Lacroix, Canvot, Munoz, Wharton, Lerma, Kamada, Mitchell, Sarr, Mateta.
Subs: Matthews, Benitez, Pino, Uche, Clyne, Hughes, Esse, Sosa, Devenny

Brighton XI: Verbruggen, Wieffer, Van Hecke, Dunk, Kadioglu, Baleba, Ayari, Minteh, Rutter, Gomez, Welbeck.

The M23 derby is one of my favourite games.
Crystal Palace won it home and away last season, but it is so hard to call this time.
The two teams are next to each other in the table, with Oliver Glasner's sitting ninth and Brighton one place behind them in 10th.
Both teams won comfortably last week too, but Palace played in the Conference League on Thursday and that is going to affect them.
Without Europe, I probably would've gone for the Eagles to win but, the more I think about it, the more I think the Seagulls will get something.
Sutton's prediction: 1-1

BBC Sport senior journalist
Crystal Palace have regained momentum with three successive wins across as many competitions and are a point ahead of fierce rivals Brighton & Hove Albion heading into Sunday's Premier League meeting (14:00 GMT). BBC Sport looks at some of the talking points going into the game.
Palace back on a roll
Palace initially struggled to regroup after their 19-match unbeaten run was ended away to Everton a month ago. But after four games without a win, they have rebuilt confidence by beating Liverpool in the Carabao Cup and then Brentford in the league before turning on the style during Thursday's 3-1 European victory over Dutch side AZ.
An unrelenting fixture schedule has left little time for manager Oliver Glasner to work with the squad on the training ground and the Austrian admits his main focus is on rest and recovery. "We have to be careful in the training sessions they don't sprint too much because they have to sprint in the games," he said. "We have to prioritise."
Despite the limited time to train, Crystal Palace remain as well drilled as ever under Glasner.
They average less possession than any Premier League side bar Burnley, but their ruthless counter-attacking style continues to provide high-quality chances – the Eagles rank top for expected goals.
Both Palace and Brighton also rank in the Premier League top five this season for shots on target and big chances scored, only trailing clubs with vastly superior resources.
The Eagles are unbeaten in 11 home league games (W6, D5), their longest run since an 18-match streak in the Championship between September 2012 and March 2013.
They beat Brighton home and away last season, with the latter encounter at Selhurst Park in April ending with three red cards: two for Palace and one for Albion.
Hurzeler understand fixture's meaning to fans
Brighton, though, haven't suffered consecutive away defeats in this fixture since the 1985-86 and 1986-87 seasons. Current head coach Fabian Hurzeler said he understood the importance of games against Crystal Palace "from the first second" when he attended a 1-1 draw between the sides two seasons ago.
He believes his Brighton team started too passively in both fixtures last season and added: "You can't promise wins but you can promise that you will leave your heart on the pitch. That is what we try to do on Sunday."
