Giggs says the 26-year-old's talent means he's treated like a 'free spirit' by manager Louis van Gaal.
Giggs said: "You don't need to do a lot with him.
"He's that sort of player, he's a free spirit. He will take you from box to box really quickly and he will create and score goals.
"He gets bums off seats and he excites me. He's the kind of player you love to watch."
