Anthony Martial (hamstring) is a doubt for Manchester United after pulling up prior to the clash with the Canaries, while Marouane Fellaini is suspended, but Daley Blind and Marcus Rashford could be recalled after not featuring at the weekend.
Van Gaal confirmed it was more a precaution to not play Martial at Norwich, but it remains to be seen whether he will return.
“I cannot say that (he will come back) as we have to wait,” said Van Gaal. “We have to wait if his muscle is still tight as I don’t take any risks as he is a very important player. We don’t want a rupture. That is very important for us.”
