Rooney's attitude has matured over the last two years. Like ALL true geniuses, he is at his best when he is most fired up, passionately. And this often spills out into aggression and thuggishness. But rarely so, over the last 6 months.
Much like Cantona, and Baggio, and little Rudi Voller, he needs to be angry, or...brimming with intensity, to show what he can really do, as an artist of the game. Rooney has little problem finding that state. And when he does, he becomes much more likely to win a game, than lose a game, singlehandedly. Though the risk is there...it is diminishing.
Arsenal and Chelsea, are both much more solid, much more settled, teams, than the present Man United team. The young guns at arsenal, are not strangers to each other. As for Chelsea..they are in their finest period, despite Terry's misdemeanours, since the decent Mourinho days. To compare Drogba and Fabregas to Rooney, is unfair, without taking into consideration the players around them.
And despite the 'chemistry' that man U always possess, they have weak links in the team. Their defence is nowhere near the class of the Chelsea defence. Their midfield is nowhere near as special as the Chelsea midfield...perhaps close to the Arsenal midfield, but Wenger's lads have a fabregas in there, whereas Man U have a sporadic Valencia, a predictable korean, and an aging giggs and scholes. Nani who is brilliants far less often than he is profligate, anderson still flattering to deceive... Carrick is a decent player, but rarely world class. Losing BOTH ronaldo and Tevez, was a massive blow to the team. holes which have not yet been filled. Rio ferdinand has been plagued by ignorance...Vidic too long on the treatment table, and as a result united have been stretched defensively. Whereas the Chelsea defence, has held very firm indeed. And ALL of their back line are threats at set pieces...and in general. Their fullbacks give wicked width and penetration up the flanks.
