Arsenal will assess Bukayo Saka on Thursday after he was forced off against Crystal Palace with a calf injury.
Winger Saka came off at half-time after a controversial challenge, late challenge from Palace midfielder James McArthur which Mikel Arteta insisted should have resulted in a red card.
Ahead of Arsenal’s return to action against Aston Villa on Friday night manager Arteta said: ‘We have two or three players that finished the game with some issues and we have to review them today. He (Saka) hasn’t trained yet so we have to assess him today and see how he is.
