New signing Henrikh Mkhitaryan is cup-tied for Arsenal's Carabao Cup semi-final second leg against Chelsea on Wednesday night.
The ex-Manchester United man appeared in the quarter-finals for his former club and is therefore ineligible to make his Gunners debut.
Aaron Ramsey (illness) and Nacho Monreal (leg) are unlikely to be involved while Olivier Giroud (hamstring) and Danny Welbeck (groin) will definitely miss out for Arsene Wenger's side.
The first leg at Stamford Bridge was drawn 0-0 while Manchester City await the winners of tonight's tie in next month's final.
Expected line-up: Ospina, Bellerin, Mustafi, Koscielny, Kolasinac, Elneny, Wilshere, Xhaka, Ozil, Iwobi, Lacazette
