There's something wrong, at least, with him.
I don't know him very well tbh, you surely know him better than me and know what he did with his previous clubs/teams and players.
Every time I watch an interview of him or whatever, he seems to have that "false" smile in his face that leads me to feel he's lying or hiding something...
He used to have sex with player's girlfriends at Southampton. He also kept Tevez and Mascherano on the bench for West Ham.
