20 13, Bayern slaughtered Barcelona. 20 14 hit Real Madrid because of tactical mistakes, and 20 15 hit Barcelona because of serious injuries, so Bayern could hardly start. 20 17 against bayern's real Madrid, Hummels boateng played with an injury and beat real Madrid in the second round of overtime. C Ronaldo scored a veritable offside goal and a controversial offside goal in two knockout matches. Where to talk about crazy goals?
