Nacho Monreal will miss Arsenal's Premier League clash with Manchester City after sustaining an injury in Sunday's Carabao Cup final.
The Spain international was forced off in the 3-0 loss to City with a back problem, which has also ruled him out of Sunday's trip to Brighton.
Arsene Wenger has no other fresh injury concerns and can recall January signing Henrikh Mkhitaryan, who was cup-tied at Wembley.
Provisional squad: Cech, Ospina, Holding, Mustafi, Chambers, Koscielny, Mertesacker, Bellerin, Nelson, Kolasinac, Maitland-Niles, Xhaka, Elneny, Wilshere, Ramsey, Ozil, Iwobi, Mkhitaryan, Welbeck, Aubameyang.
