When Rooney is 'on' I'd say he's the best player in the league and can pretty much single-handedly win big games for United. He goes through spells of playing like a pub footballer though and these seem to be getting more frequent. Like some have said I wouldn't be surprised if he only has a couple more seasons left as a top player due to fitness.
His ability as a player aside, I Think Rooney hates us more than pretty much any player out there. So just on that basis I'd say no. I'd take Ronaldo in a second though.
