The Gunners board the plane to Germany on the back of an engrossing 2-2 draw with Thomas Tuchel's men in the first leg, ending a three-game run of 5-1 defeats against the Bavarians.
Bukayo Saka's early strike gave Arsenal the lead, but Serge Gnabry and Harry Kane — two men who spent time in the Gunners academy setup — turned the tie around thanks to defensive calamities from Arteta's troops.
However, smart work from Gabriel Jesus saw the Brazilian tee up Leandro Trossard for a second-half leveller, leaving the tie on a knife-edge ahead of this week's eagerly-awaited second leg.
Both European behemoths reunite on the back of painful domestic experiences, though, as Bayern's 11-year reign of Bundesliga supremacy was officially ended by Bayer Leverkusen, while the Premier League title is out of Arsenal's hands owing to a 2-0 loss to Aston Villa.
Martin Odegaard, Bukayo Saka involved in full trainingDuring the defeat to Unai Emery's side, Arteta was forced to bring captain Martin Odegaard off in the second period, explaining that the Gunners captain felt something and could not continue in the dying embers.
Meanwhile, Saka — who has constantly been in the wars this season — was also seen hobbling towards the end of the match, sparking familiar fears about the 22-year-old's physical condition as well.
