Mourinho in his prime was right up there but most of his achievements came in the space of 10 years. He has many great attributes but the ability to adapt his style to suit the changing game isn’t one of them.
I think his treble with Inter and winning the CL with Porto are greater individual achievements than anything Pep has done, when you take the quality of squads into consideration.
However he didn’t change the way football was played across the globe. Pep has undoubtably done that, even if he’s never really tested himself with lesser teams. His style of football has also stood the test of time. He’s been doing it now for 15 years and is still playing with a style no one really knows how to stop or better.
This would match my opinion. Jose's achievements in his first decade of management are as impressive as anything any manager has done that I can think of. Unfortunately he's become a bit of a caricature and all that drama has distracted from that. Plus Peps focus on tactics and "philosophy" appeals more to some people than Jose's more traditional tactics and motivational skills.
