Most decorated definitely.
It's kind of easy to look and give him credit like this. But fact is we never saw him manage not the best team in the world, like most of the managers do before they get to manage a top team, or in his case instantly a team that has the best talent in the world.
Just a good example was bayern, and how he destroyed them. Just a year before that team was a machine, best in the world, but he managed to screw things up for them quite fast.
Anyway, I doubt he will ever accept a job where he can be truly tested. Winning a league with bayern is not exactly a miracle work.
Oh and he's disgusting too.
