There are two separate areas here, player/club behaviour and official mistakes. The second one is easy, in that it is actually very likely to even itself out over a season - and if anyone thinks an official is biased, they should put their money where their mouth is and take them to court.
Player/club behaviour is, IMHO, more serious. Too many managers use the old Millwall "everyone hates us" as a major motivational tool. Ferguson seems to have little else in his armoury, and, while it is effective he is not going to change. And we see that nice restrained Mr Terry using the same approach at Chelsea (OK, so he ain't the manager, but what does that say about how the club is playing?). And this will inevitably lead to over-pumped players, driven by anger and hate - and swearing at cameras, referees and anyone who passes. Other managers this season have made the same observation, warning that they are sending players out so pumped-up that serious injury will happen. IMHO, the only answer must be to punish the club, not the player. Even Rooney is not indispensable, but something like a 30-point deduction, or removal of consideration for European competition for the next three seasons would hurt. Impose something like that after, say, three club offences and the managers would have to do what they are supposedly already doing, manage their players.
