Arsenal will be hopeful Mesut Ozil overcomes illness to be involved in Wednesday's Premier League visit of Huddersfield.
The Germany international missed the 1-0 win at Burnley on Sunday but was expected to train on Tuesday in an attempt to be available.
Alex Iwobi (leg) is definitely missing, as is long-term injury absentee Santi Cazorla (ankle) but they are Arsene Wenger's only two sidelined players.
Arsenal face a crunch clash against Manchester United at the weekend but the Frenchman plans to play a full-strength side against the Terriers.
He said: "The most important game is tomorrow [Wednesday]. We have a good chance to take three points at home and that is all that matters. We have a big squad to deal with it.
"It is a massive game for me. They didn’t deserve to lose against City.
"They had to play 46 games in the Championship and have proven they are ready for a fight. They are dangerous for every Premier League side."
Provisional squad: Cech, Ospina, Mertesacker, Holding, Koscielny, Mustafi, Chambers, Monreal, Debuchy, Bellerin, Nelson, Kolasinac, Maitland-Niles, Ramsey, Wilshere, Xhaka, Elneny, Ozil, Walcott, Sanchez, Welbeck, Lacazette, Giroud.
