Arsenal have excluded goalkeeper Alex Runarsson from their Europa League squad.
The north Londoners have opted to include new signing Mat Ryan, who arrived on loan from Brighton.
In-form Brazilian, Gabriel Martinelli and another loan signing, Martin Odegaard, also made the list.
Arsenal have named their 25-man squad that will take part in the rest of the competition this season.
Initially, Martinelli was out of the squad for the group stages as he was expected to miss nearly all the games due to injury.
