Do you think rooney is not playing very well because tevez has taken his role?

what tevez does now is rooney's job but they can't both be doing that so rooney is having to play further up the field and im really not happy with that becasue it takes a lot away from his game.i think this is largely the reason why he's been very quiet this season.at the moment tevez is much more of a threat than rooney so you ant leave him out but then fergie would never leave rooney out either even when saha comes back..bit of a dilemma.hope it all works out
