Arsenal’s win in Belgrade was their first in three meetings with Crvena Zvezda – they also met in the 1978-79 UEFA Cup last 16 when Arsenal were eliminated after they lost 0-1 on the road and then drew 1-1 Highbury.
 
Arsenal have only ever won their opening four games in the group stages of European competition once – winning their first five in the 2005-06 Champions League en route to the final.
 
The Gunners are unbeaten in all six of their home UEFA Cup/Europa League games under Arsene Wenger, winning the last five in a row after drawing with PAOK Salonika in 1997-98.
 
Arsenal have only failed to score in one of their last 26 games in European competition, with that failure coming at the Emirates against Barcelona in February 2016 (0-2).
 
Crvena Zvezda won their opening away game in this competition at FC Koln – excluding qualifiers, they’ve not won back-to-back away matches in European competition since November 1991 (a run of four), en route to winning the European Cup.
 
The Serbian side have been shown 10 cards in the group-stages so far, including a red in the reverse fixture against Arsenal (9 yellows) – no side has been shown more in the competition so far (Hoffenheim, 10 yellows).
 
No side has used more different players in the Europa League than Arsenal this season (22, level with Hertha Berlin and Vitoria Guimaraes).
