Arsenal will be facing Atletico Madrid tonight with the tie locked at 1-1 hoping to give Arsene Wenger a shot at European glory by advancing into the Finals before he bows out.
Wenger, who is bringing down the curtain on his 22-year Arsenal reign at the end of the season, will take to the home dugout as manager for the last time on Sunday when Burnley travels to the Emirates Stadium.
Arsenal have no fresh injury concerns ahead of the second leg of their Europa League semi-final against Atletico Madrid on Thursday.
The Gunners head to Spain with the tie finely poised at 1-1 but have the boost of a fit Henrikh Mkhitaryan, who returned from a knee injury at the weekend having sat out the first leg.
Meanwhile, Arsenal nemesis Diego Costa is set to start tonight after coming through his return from injury against Alaves on Sunday unscathed after staying on the bench for last week’s Europa League semi-final first leg.
And Atletico trained on Tuesday with the Brazilian-born Spain striker in Simeone’s likely starting side to face the Gunners.
Costa is expected to replace Kevin Gameiro and start alongside Antoine Griezmann whose late equaliser earned Atletico Madrid a 1-1 draw at the Emirates
