Well, United got only one CD because Blackett took his chance. I think that counts as giving a chance to a youngster. About Thorpe and McNair, I agree, they only got the chance because everyone else was injured. We'll see in January if United will bring CD or will Thorpe and McNair will become backups.
Hard to judge on one game at home to inferior opposition. Good shift by those two but you have to remember that even Josh McEachran dominated in the CL against teams when he was 17 and now he can't even get a game for Vitesse in the Dutch League
