Mourinho needs a team he can craft in his own image, a team in which he’s essentially the only personality. I think he and Rafa are similar in that way, though they go about it in different ways. As players become bigger personalities and “brands” themselves, someone like Mourinho will struggle to impose his will.
He’d be a tremendous hire for a club like us (under a different owner). He’s an asshole, but he’s still one of the brilliant minds in the game.
