Van Persie is excited by 17-year-old Mason Greenwood and the Dutchman is a "big fan" of Rashford, too.
"(Rashford) has it all," he says. "But at Manchester the bar is so high.
"You have to do everything and that is fair – you're playing at one of the biggest clubs in the world so people can ask that. People want consistency, although he's young."
Van Persie adds: "You always have people asking for more and they're right, that's why you're there."
