I haven't seen this discussed yet and it came up in a conversation today. I was shocked to read it. From the Champions League rulebook:
2.03 The UEFA Champions League titleholder is guaranteed a place in the group stage even if it does not qualify for the competition through its domestic championship.
If the titleholder comes from an association entitled to four places in the UEFA Champions League and qualifies for the UEFA Europa League through its domestic competitions, the lowest-ranked club of the association’s UEFA Champions League representatives is automatically transferred to the UEFA Europa League (into the latest possible round where there is a vacancy). In this case, the number of places to which the titleholder's association is entitled in the UEFA Champions League and the UEFA Europa League does not change.
So... all Spurs fans out there, I realize you may feel a bit dirty rooting for the Germans to beat the English, but start holding your breath now that Bayern puts up eight for the final.
Or we could just win 3rd. That would work too.
