Depends on what you consider 'cool' to mean. If you have to look the part to be cool then I think he's cool. I mean he doesn't model a 5 dollar scarf like Mancini, but he dresses sharply. If you have to be charismatic to be cool then maybe he's not as cool as Mourinho, but then who is? If you have to be laid back to be cool then he's the least cool guy in the world.
