Arsenal have Mesut Ozil, Jack Wilshere and Petr Cech available for Thursday’s Europa League semi-final first leg against Atletico Madrid.
Midfielders Ozil and Wilshere, and goalkeeper Cech missed Sunday’s win over West Ham with minor injuries.
Striker Diego Costa has been named in a 20-man Atletico squad for the trip.
Boss Diego Simeone said at the weekend the Spain forward had “no chance” of being fit for the game at Emirates Stadium because of a hamstring injury.
He has missed three games since limping out of the quarter-final second leg against Sporting Lisbon.
Costa has scored six goals in 18 games since his move from Chelsea.
Full-back Juanfran will miss Thursday’s game because of a hamstring injury.
