Arsenal boss Arsene Wenger will decide whether Alexis Sanchez plays in Sunday’s Community Shield final against Chelsea at Wembley.
Forward Sanchez returned to training on Tuesday after illness, having taken an extended break after his participation in the Confederations Cup with Chile.
Chelsea striker Diego Costa will not start, after being told he can leave by boss Antonio Conte.
The game is to soon for forward Eden Hazard and midfielder Tiemoue Bakayoko.
Blues boss Antonio Conte expects the pair to also miss next week’s Premier League opener against Burnley as they look to gain match fitness.
Hazard had ankle surgery over the summer and Bakayako, a £40m summer signing from Monaco, had a knee operation.
Strikers Alvaro Morata and Michy Batshuayi could start together, while Pedro could play wearing a mask to protect a facial injury.
Gunners centre-half Laurent Koscielny and Chelsea wing-back Victor Moses are both allowed to play, despite serving suspensions.
Arsenal’s club-record £46.5m signing Alexandre Lacazette and new defensive arrival Sead Kolasinac are in line to feature, but Francis Coquelin (ankle), Gabriel (knee) and Jack Wilshere (leg) will miss out because of injury.
Sanchez, 28, is entering the final year of his deal at Emirates Stadium and, amid reported interest from other clubs, Wenger has said: “He will stay and he will respect that.”
He could be left out of the squad on Sunday though, after a truncated pre-season, as could Germany defender Shkodran Mustafi, who also featured in the Confederations Cup.
The traditional season curtain-raiser is a repeat of last season’s FA Cup final, in which Arsenal beat Premier League champions Chelsea 2-1.
