Ole Gunnar Solskjaer says he will use his youngsters next week against Rochdale.
Teenagers Mason Greenwood, Angel Gomes and Tahith Chong all started in Thursday's 1-0 win over Europa League, with the former nabbing the winning goal.
And Solskjaer isn't afraid to use them again in next week's Carabao Cup clash.
"We wouldn't throw them in if they weren't ready. Some of them won't play against West Ham but will play against Rochdale midweek.
"If you want to make it as a Man Utd player you need to handle the fans. Mason won the game for us. Angel [Gomes] did well and [Tahith] Chong showed glimpses. Two clean sheets so now we're looking forward to Sunday.
"The first four or fives weeks it's just one game a week so you don't really get to utilise everyone."
