It is the end of an era for at least one of the clubs taking part in the semi-finals tonight.
As Arsenal prepare to say goodbye to Arsene Wenger, they begin their Europa League semi-finals with a home match against Atletico Madrid. It is Wenger’s last chance to get a trophy for the Gunners, who if they do get to the final will take on either Marseille or the bizarrely named FC Red Bull Salzburg.
Arsenal v Atletico Madrid is on BT Sport 2 at 19.30 (kick-off 20.05).
Marseille v FC Red Bull Salzburg is on BT Sport 3 at 20.00 (kick-off 20.05).
