Manchester United boss Erik ten Hag included six youngsters in senior training on Friday.
United meet Wigan Athletic in the Third Round of the FA Cup and it could offer the chance for Ten Hag to test several youngsters.
Maxi Oyedele, Omari Forson, Isak Hansen-Aaroen, Joe Hugill, Shola Shoretire and Sam Murray joined September debutant Dan Gore in senior training on Friday.
Hugill, Forson and Shoretire are all in new contract talks with United.
Also training was Willy Kambwala, who is tipped to start the tie.
