I'm really tired of this argument tbh, Pelligrini, Ancelotti and Jose Mourinho had the same squad. Barcelona possibly had the greatest Team in football history and Pep couldn't win 2 in a row never mind 3.
You can get lucky once (Di Matteo), but if you think he won 3 UCLs in a row because he had a top team and was lucky name me another modern manager that has had a top team and won 2 in a row ? Bayern didn't manage it, Barcelona didn't manage it, we got close with Fergie (we also had possibly our greatest team of all time those years as well). If you think that Zidane just told those Madrid players go out lads and have fun and won 3 UCLs idk what to say
God help every manager in the world If winning 2 leagues and 3 UCLS in 5 years is considered a huge question mark in football management.
