I don't hate Pep, i simply have doubts...is he that good?
IMO it is not a given that Bayern win Bundesliga every year. This year's Dortmund would have been champion most years for example.
How do you think Bayern consistently stomped the league for three years, no matter who was on the field? They didn't before him and I'm quite confident they won't when he's gone.
They seem to win almost every game so comfortably, teams started collecting yellow cards on purpose so their players would be banned against Bayern. Losing even before kick-off is unheard of to me on this level.
Up until the 2nd half of this season Guardiola had a different game plan every week, greatly adapting to each opponent, setting up his team to exploit weaknesses and suppress strengths. Often his ideas did not work too well and he adapted within 20-30 mins and if necessary again and again.
Bayern don't just control games by default.
Opponents need to be strangled. Your own players need to be put in a position to succeed. Other than maybe Robben nobody in that squad is going to win you the game if you just let them play.
Obviously he did not achieve perfection. As you said, Bayern tend to lose form in spring and important players seem to get injured unusually often, especially this time of the year. May be Pep's fault, may be someone else's, may just be bad luck, I don't know.
Is there another coach up there with him as far as consistently winning games over multiple seasons, though? Can only think of Simeone (who might just be even better). Maybe Allegri at Juve also?
That is only talking about success and not even mentioning what he offered to football as a whole. Memorable & historically dominant performances vs Roma, Juve & now Atleti for example. Tactically he build an unrivalled counterpress and invented new roles to make use of his players' strengths, like SB/DM-hybrid-Lahm & half-space-Libero-Alaba.
I'm confident by next year I won't be the only neutral Bayern watcher who's gonna miss him. Pep games were always interesting. Often I watched even though I knew the outcome. Let that sink in..
Did he succede at Bayern? No. Bayern and Pep will both agree with that.
I'm not so sure they'd actually agree, especially Pep himself.
edit:
I'm not even sure why I wrote this post. I disagree with evaluating coaches by points/achievements. Performance is more indicative of goodness/quality to me.
