Rooney is a team player just as he is an headline player.
Rooney will do all the horse work and lay it on a plate for players like Ronaldo to take all the glory, which happened many times in Ronaldo's United years and he's happy to do this, whereas many players would not be. When Rooney is having one of his 'off' games he can still come up with a moment of brilliance and win a football match (like against Chelsea) he's the only player i can think of who can play in several positions and do them all WC, he can also do everything on a football pitch (score brilliant goals, score 30+ goals a season, pick out Xavi/Scholes long like passes, play eye of a needle passes, tackle, tracks back, is all over on a football pitch)
No player in the world is talked about by players & coaches more than Rooney and there's a reason for this, he's fantastic - When he put a transfer request in at United last season during a time, when he had a poor world cup/started off the season in bad form/didn't look fit and had problems off the pitch, every team and coach still wanted him (Madrid/Barcelona included).
Why? He's a players and coaches dream.
