David Moyes must decide whether to keep Wayne Rooney at Manchester United this summer.

The Daily Mail says it is understood Rooney's sense of dissatisfaction that has fluctuated wildly all season is not with life at United but, specifically, with life under Sir Alex Ferguson.

The 27-year-old has grown frustrated this season with his role in the team - when he has been picked - and indeed with the manner in which Ferguson has made regular references to his fitness.

Moyes is the man who gave Rooney his debut at Everton as a 16-year-old and subsequently oversaw a £23million move to Old Trafford in 2004.

As such, Moyes, as much as anyone, is acutely aware of his talents but also of how challenging he can be to manage.
