Should mainly be Rooney's choice imo but you cannot understate how important it is for whiskey nose to ensure his best player is not burnt out un-necessarily. I remember when Gerrard and Carragher decided to forget England for a while during 02 world cup and concentrate on getting fit for Liverpool for the next season. It cannot be said how good the pair of them have been since then and how much they've helped Liverpool with their choice. Ferguson will be thinking the same thing with Rooney, totally understandable.
