"I think he will," Ruud said. "That is what the manager does: he makes you feel strong and gets the best out of people.
"Robin's style – the way he wants to play, the way he likes to play – fits United so well. I'm happy for him that he’s made such a great start because he deserves it. He’s a great player and I hope he can continue like this for a long time.
"It’s not just scoring goals, either. He's great in his ability to get involved in the play as well as his finishing, which is fantastic."
Van Nistelrooy was speaking to ManUtd.com, PA Sport and Manchester Evening News.
