As soon as this season's Champions League draw was completed, Group C stood out above all others.
Straight off the bat, there was the prospect of Robert Lewandowski getting an immediate reunion with Bayern Munich after leaving the 2020 champions for Barcelona. The Polish international drew a blank in Bavaria, with Lucas Hernandez and Leroy Sane handing Bayern victory, but will have an opportunity to gain revenge at Camp Nou at the end of October.
That's not the only heavyweight clash in the group, though, and not the only one with a history of players turning out for both sides. After losing home and away to Barca in the 2019-20 group stage, Inter Milan have faced Real Madrid in each of the last two seasons but now have a chance to try their luck against Xavi's team.
