Yes, the Dutchman is certainly past his peak now, but he still has the quality to play a backup role at Old Trafford, especially with Wayne Rooney now the only option up front and playing so poorly so far this season. RVP, meanwhile, has got off to a scoring start in Turkey and must have at least a year or two left at the top level.
