Arsene Wenger has made six changes to the side which beat Stoke City on Saturday for tonight's Champions League group stage opener against Dinamo Zagreb.
David Ospina replaces Petr Cech in goal and there are recalls for Mathieu Debuchy and Kieran Gibbs in the full-back spots, with Hector Bellerin absent from the squad altogether.
In midfield, Mikel Arteta and Alex Oxlade-Chamberlain return at the expense of Francis Coquelin and Aaron Ramsey, while Olivier Giroud is preferred to Theo Walcott in attack.
Cech, Nacho Monreal, Coquelin and Walcott all take their places on the bench, but Per Mertesacker is not included in the squad after being involved in a car crash on Monday.
For the hosts, Marko Pjaca and El Arbi Hillel Soudani, who have each scored three times in the Champions League already this season, both start but former Manchester United and Wigan Athletic striker Angelo Henriquez has to make do with a place on the bench.
Dinamo Zagreb: Eduardo; Pinto, Sigali, Taravel, Antolic; Machado, Ademi; Pivaric, Soudani, Fernandes; Pjaca
Subs: Jezina, Benkovic, Matel, Coric, Rog, Henriquez, Hodzic
Arsenal: Ospina; Debuchy, Gabriel, Koscielny, Gibbs; Arteta, Cazorla, Ozil; Oxlade-Chamberlain, Sanchez; Giroud
