The fixture that could define Arsenal's season will kick-off at the Emirates tonight, with Mikel Arteta's side needing to overturn a first-leg defeat to Villarreal in the Europa League semi-final.
The competition is the Gunners' only realistic hope of securing European football for next season, having slumped to ninth in the Premier League with four games to go.
Arteta's men are 2-1 down after first-leg defeat in Spain, where Dani Ceballos was sent-off and Nicholas Pepe bagged a critical away goal in the second-half.
