Arsenal are likely to be without Thomas Partey for Sunday’s Premier League visit of leaders Manchester City.
The Ghana midfielder has been struggling with a hamstring injury and is not expected back in time to face Pep Guardiola’s in-form side.
Kieran Tierney came off the bench in the Europa League draw with Benfica following a leg injury and could return to the starting XI.
City are waiting on free-scoring midfielder Ilkay Gundogan and will assess the Germany international before heading to London.
Gundogan took part in some of Friday’s training session after missing the 3-1 midweek win at Everton with a groin injury.
Sergio Aguero could be involved with City manager Pep Guardiola confirming every member of his squad is fit with the exception of defender Nathan Ake.
Arsenal provisional squad: Leno, Runarsson, Ryan, Bellerin, Chambers, Gabriel, Holding, Luiz, Mari, Cedric, Ceballos, Elneny, Xhaka, Saka, Odegaard, Smith Rowe, Willian, Aubameyang, Lacazette, Nketiah, Martinelli, Balogun.
Manchester City provisional squad: Ederson, Steffen, Walker, Cancelo, Dias, Stones, Laporte, Garcia, Zinchenko, Mendy, Fernandinho, Rodri, De Bruyne, Silva, Gundogan, Sterling, Torres, Mahrez, Foden, Jesus, Aguero, Doyle, Bernabe, Gomes.
