The PFA and Football Writers' Association award winner has scored 33 times this season, offering Utd fans a much needed scoring option following the loss of Ronaldo and Tevez last summer.
United even jumped to 86 league goals over the course of the campaign, a remarkable step up from the 68 accrued last season.
So he’s helped to up the goal tally and his manager doesn’t seem too concerned about Rooney’s latest injury.
“I think he's aggravated the groin again. I don't think it's serious – he'll be OK for England,” said United manager Alex Ferguson.
Well, we’ve been here before, but at least this time England aren’t alone in having injury worries.
Spain’s Fabregas, Torres and Xavi may struggle to play regularly in South Africa.
Holland’s Robin van Persie is only just coming back from injury.
The good news is Socceroo legend Harry Kewell will probably be fit after missing the last twelve years with hair band problems. That’s good news for everyone else but not Australia.
