Why would they like him?.....well despite his comments to the fans which I think are out of order, he isn't in anyway a bad guy.
Has he tried to undermine other managers the way Mourinho does, or is he despite the frustration with him quite an interesting person to listen to. Also like i say if you were answering the same sort of questions constantly on a 20 year basis you would probably come out with stock responses.
I don't like how he's performing as Arsenal manager, that does not inform what i think of him as a man, you have a personal dislike of the man fine.....If i'm honest i think most people who dislike him on a personal level boils down to familiarity breeding contempt.
I honestly think if you put everything you are into a job and people were criticising you for it rightly or wrongly, you'd be pretty sour as well. That's not the same as saying he is right to criticise the fans, but at the same time there is something you can understand about it.
