8. Five European Cups in a row (Real Madrid)
The Cristiano Ronaldo-inspired Real Madrid won three Champions League titles in a row between 2016 and 2018. Incredible, right?
As impressive as it is, however, it turns that there was an even more formidable Los Blancos squad once. It’s hard to imagine, but the team from 1955 to 1960 was something else.
Real Madrid won five consecutive European Cups, with the legendary Alfredo Di Stefano leading the charge.
It was frightening stuff indeed as no one in Europe could do anything about it.
