Midfielder Mesut Ozil has been left out of Arsenal's Europa League squad for the forthcoming campaign.
The 31-year-old's future at the club remains uncertain after being persistently left out of the side by manager Mikel Arteta.
The Germany international has not played for the club since March.
New £45m signing Thomas Partey has been included in the squad before their first Group B fixture against Rapid Vienna on 22 October.
The former Atletico Madrid midfielder joined the Gunners on deadline day.
The Gunners will also face Irish side Dundalk and Molde from Norway in the group stages.
