The Champions League (or European Cup) has been running for over 60 seasons and remarkably, in that time period, the trophy has been shared between a total of just 22 teams.
Juggling continental concerns with domestic responsibilities can be a difficult task and it is rare that a team dominates in both spheres, with success in one competition usually inhibiting it in the other.
However, it can and has been done, with plenty of teams doing so in the days of the old European Cup - when it was a straight knockout tournament - as well as in the modernised Champions League era.
