Crystal Palace sit a point above Arsenal having gone three matches unbeaten in the Premier League.
The Gunners, however, can go level on points with Tottenham Hotspur and Wolverhampton Wanderers ahead of their matches later in the day with a second win and a first away from home under new head coach Mikel Arteta.
Team news
Cenk Tosun is in line for his Palace debut after completing a loan move from Everton on Friday. The striker goes straight into the squad, along with fit-again Wilfried Zaha, Max Meyer and Jairo Riedewald.
Luka Milivojevic is suspended after his FA Cup red card, but the Eagles are awaiting the result of the appeal against it.
Arsenal's Hector Bellerin (hamstring) will be assessed, while the Gunners remain without Calum Chambers (knee) and Kieran Tierney (shoulder).
