Arsene Wenger takes charge of his final European home match for Arsenal this evening.
Wenger announced earlier this week that he will be stepping down from his position at the end of the season after almost 22 years in charge.
His team face Atletico Madrid in the first leg of the UEFA Europa League semi-finals at the Emirates.
The match will be shown live on BT Sport 1 from 7.30pm with live streaming on BTSport.com and via the BT Sport App.
Arsenal and Atletico have never met in UEFA competition, though the Gunners did beat their Spanish opponents 2-1 at home in the 2009 pre-season Emirates Cup.
Both of these sides survived second-leg scares in the quarter-finals with the Gunners eventually prevailing 6-3 on aggregate against CSKA Moscow (4-1 home, 2-2 away after trailing 0-2) and Atletico edging Sporting 2-1 over the two legs (2-0 home, 0-1 away).
