Shola Shoretire wasn't included in Manchester United's U21 side that faced Man City on Saturday due to his first-team commitments this week.
The 18-year-old was part of the United first-team squad that faced Real Sociedad in the Europa League on Thursday night and was not rushed back into action for the derby encounter at Leigh Sports Village.
Shoretire was an unused substitute as United won 1-0 in San Sebastian, with fellow academy graduate Alejandro Garnacho scoring his first competitive goal for the club.
