I've noticed this when I look at the comments under articles on the Guardian website (which I stopped doing after I realised that there's about 10 regular and coherent contributers and 90% of the rest only post under Liverpool or Man U results).
Basically:
Nobody gives them enough credit
Everybody's against them.
Their team doesn't cost any more than anybody else's because they've never spent £80m on a single player.
They're not financially doped because their accounts show they make a profit.
I don't get the impression that winning actually brings them any satisfaction at all. It's mostly negative "take that UEFA/FA/United/Liverpool" rather than any positive reaction.
And yes, the City fans I know personally are lovely, but I could say that about almost any club.
Probably because most of them aren’t real football fans, just glory hunters. Haven’t been to a game, probably aren’t even from Manchester.
One word of caution, if things continue to progress here we’ll start to pick up these kind of fans. We’re an attractive club to watch right now.
