Arsenal could have Emile Smith Rowe available for Thursday’s Europa League round-of-32 first leg against Olympiacos.
The attacking midfielder suffered a muscular injury in the recent win at Leicester and missed Saturday’s draw at Burnley.
Manager Mikel Arteta has no other injury concerns but does have Sunday’s north London derby at home to Tottenham to consider when picking his team in Athens.
The Greek side knocked the Gunners out of European competition last season.
Arsenal provisional squad: Leno, Ryan, Bellerin, Chambers, Gabriel, Luiz, Mari, Cedric, Ceballos, Elneny, Partey, Xhaka, Saka, Odegaard, Smith Rowe, Willian, Aubameyang, Lacazette, Nketiah, Martinelli, Balogun.
