Assuming RVP goes to United (which I think is very likely at this point). I think the way he'll fit in there is through rotation. Fergie loves rotation as it is, but RVP adds further dimension to that. I think people are forgetting too that RVP only played so often for Arsenal last season because we couldn't afford to rest him as our back-up is shit. At Man Utd, I think he'll be happy to only play once a week due to his age and injury record. With RVP around too, Fergie will be able to rest Rooney more often too. So I do think there will be plenty of opportunities for Welbeck, Hernandez etc.
"Every man's heart one day beats its final beat, his lungs breath their final breath. And if what that man did in his life, makes the blood pulse through the body of others, and makes them believe deeper in something larger than life, then his essence, his spirit, will be immortalised by the storytellers, by the loyalty, by the memory, of those who honour him and make whatever the man did live forever."
