Calling it "abuse" is a serious fucking insult for a start. He's being mocked because he's shit, that is not abuse.
Secondly, he's not this innocent guy that's done nothing wrong, hes a wanker. people seem to be forgetting he was convicted of assault of a police officer and attempted bribery and is yet to pay any consequence.
He's also decided to stay at united, where he's widely hated and declined a move away purely because of the money, which is his right to do so but you accept the shit you will inevitably get for doing that.
