And people who say he was much better as a young player . . .
Personally, I think he was more superficially exciting back then, with his charging dribbles and what have you, but not necessarily better. And I reckon there's a tendency for people to remember that era based on the highlight reels, which obviously don't show you that he was prone to the odd shoddy game then as well.
His average goal scoring contribution per 90 in his first three seasons at United - when he was apparently young, brilliant, exciting Rooney - was 0.45.
His average goal scoring contribution per 90 in his last three seasons at United - when he's apparently been boring, in decline, no longer quite-as-good Rooney - has been 0.87.
Almost *twice as productive* over his last three years than his first, then.
And I don't think he's much less exciting than he was anyway. He can still volley goals in from the half way line, smash them into the top corner from 25 yards, etc.
It's just that maybe the novelty has worn off somewhat now, and the unexpected has become the expected.
