Those teams all won cups when the PL wasn't as strong.
Football goes in circles especially in Europe, Italy hasn't won a CL since Inter in 2010, Madrid and Barca won the CL when the PL, Serie A was weak and Bayern won one out of that 6 year span when those 2 Spanish teams had stranglehold on the competition, those 2 Spanish teams had it so good.
It's the PL time now to be top of the food chain in Europe, it's like the dominant period England had when English clubs had the European Cup for 6 years in a row from 1977 to 1982.
No better time for Pep and City after a 5 year spend of £950 million to finally win one in these "turbulent times".
