Pep's Barca used to absolutely annihilate Real Madrid every time they played them at their peak. I seem to remember a 6-2 at the Bernabeu and a 5-0 at the Camp Nou. Proper footballing lessons. This Madrid team still routinely get dispatched by Barca in El Clasicos. Also they've been quite fortuitous with a couple of those CLs. Atletico had them beat in 2014, needed pens in 2016, even this year Bayern were robbed against them by all accounts. Look at both finals Barca beat Utd, complete one way traffic. I know the semi with Chelsea in '09 was a bit controversial but that was an anomaly.
