Aaron Ramsey and Olivier Giroud return to the Arsenal starting line-up for the Champions League game against Ludogorets Razgrad in Bulgaria.
Both players are fit again after injury and came on as substitutes in Saturday’s 4-1 Premier League win at Sunderland, where Giroud scored twice.
Ramsey starts a match for the first time since suffering a hamstring injury against Liverpool on the opening day of the season. Alexis Sanchez is also in the side.
Carl Jenkinson comes in at right-back in place of Hector Bellerin, who did not travel with the squad.
Neither did Theo Walcott, Santi Cazorla and Nacho Monreal, who are all nursing injuries and missed the Sunderland game.
Arsenal are looking to maintain their position at the top of Group A, which they lead on goal difference from Paris St-Germain, who are away to Basel.
Arsenal: Ospina, Jenkinson, Musafi, Koscielny, Gibbs, Zhaka, Coquein, Ramsey, Ozil, Sanchez, Giroud.
Subs: Cech, Gabriel, Holding, Elneny, Matland-Niles, Oxlade-Chamberlain, Iwobi.
