For me at least, it's that 'US arrogance' that makes him unlikeable, at least he comes across that way. He came into English football seemingly acting like he has football 'all figured out', as though he has 'cracked the system'.
"I'm gonna fuck this helmet guy and that Russian broad off, who needs these roles in a club anyway? I just need to spend 600mil on superstars, that will win me things, it's that easy guys - money talks, football walks. After that, I'll just hand this star-studded squad over to a YOUNG and UPCOMING coach. Who even needs experience managing big players? Young is always better. Hah, this FFP nonsense can fuck off too, wait till they get a load of my lengthy contracts. ...Man, this European football should really take a look at how us Americans do things and do an annual, meaningless all-stars game, because why the hell not."
