Arsenal squad vs Atletico Madrid revealed
Arsenal take on Atletico Madrid in the first leg of the Europa League semi-final on Thursday.
The Gunners will hope to secure a first-leg lead against Diego Simeone's men at the Emirates, such is the home form of the La Liga side.
The clash will be Arsene Wenger's final home European match in charge of Arsenal after he announced he will leave this summer.
There have been some special nights, first at Highbury and now the Emirates, and Wenger will hope for one more against Atletico.
Arsenal welcome back Jack Wilshere, Petr Cech and Mesut Ozil for their Europa League semi-final first leg against Atletico Madrid on Thursday.
Wilshere, Cech and Ozil missed Sunday's win over West Ham as they were given time to recover from ankle, hip injuries and illness respectively. Sead Kolasinac (ankle) is also available.
Henrikh Mkhitaryan (knee), Mohamed Elneny (ankle) and Santi Cazorla (Achilles) remain sidelined, however, while Pierre-Emerick Aubameyang is ineligible.
Atletico have been boosted by the news that Diego Costa is fit to play.
He has sat out their last three matches but travelled to London with the rest of the squad.
