Arsenal were handed an injury boost ahead of their Europa League semifinal against Atletico Madrid as Henrikh Mkhitaryan and David Ospina trained on Wednesday.
Manager Arsene Wenger said after Sunday's loss to Manchester United that Mkhitaryan and Ospina could be doubts for the second leg in Madrid after picking up knocks in that game.
But they took part in the final training session before flying out to Madrid, as did Alex Iwobi who had also been an injury doubt.
Mkhitaryan returned from a knee injury by starting at Old Trafford on Sunday but came off in the second half after taking another knock to his knee.
His return should be a big boost to an attack that struggled to convert chances in the first leg at the Emirates.
Arsenal and Atletico drew 1-1 last week despite the Spanish side playing with 10 men for most of the game.
Ospina played in the first leg after missing the quarterfinal tie against CSKA Moscow with an injury, although Wenger has yet to say whether he will stick with his cup goalkeeper or pick his normal No. 1 Petr Cech for what could be his final European game as Arsenal manager.
