Probably in a way Mourinho has been 'found out'. I'm certainly not saying there's no substance to him, because it's a fine tactician who has learned from the best. But he himself has made the other stuff much more important, the mind games, the attitude, the intimidation of referee's, the drama queening, the siege mentality, the time waisting, the violent tackles and conduct. He has blown the non footballing stuff out of proportion to create some feeling of invincability, but that only works for so long, and now his teams are proven to be vincable, vulnerable even, with all their money and class players. It's not just Chelsea, there's also Madrid.
The next club he arrives, the players probably won't buy his confidence pumping speeches, because his magic is gone. "Trust me, because I guarantee succes" is not credible anymore, the guarantee is void. Probably his days as a one of the few great managers are over, he has to go back to his craftsmanship in football itself, he's good at it, but not the best.
