Four years ago, in 2020, Bayern Munich beat Paris Saint-Germain 1-0 in the Champions League final. Tonight, they meet for the third time since. Those four years — an Olympic cycle, a World Cup cycle — is a period of time that lends itself to assessing how the two clubs, which share as many similarities as differences, have changed.

PSG manager Luis Enrique said on Monday that his team have put themselves in a "difficult" spot with a slow start to their Champions League campaign.

Real Madrid playing Liverpool in the Champions League has twice in recent years been a final between arguably the two best teams in the competition.
