Former Tottenham boss Harry Redknapp can't see Marcus Rashford starting for Manchester United in Saturday's derby.
Redknapp wrote in the London Evening Standard: "Marcus Rashford made his case to be involved, having scored the winner at Hull and followed that up with a hat-trick for England's Under-21s.
"I spoke to Ryan Giggs about him during the summer and he told me people at United all think he's the real deal but Mourinho isn't in the business of worrying about helping kids in their careers.
"Winning is the only thing that matters and he won't drop Zlatan Ibrahimovic for a game like this. Anthony Martial is better off the left, so the best Rashford can hope for is a cameo off the bench."
