The game with Liverpool, scheduled for this Saturday at 11:00 GMT at the Aon Training Complex, has been rearranged for Saturday 11 April at the same venue with the same kick-off time.
The reason for the change is due to United's FA Youth Cup fourth-round tie against Norwich City, which takes place on Tuesday 21 January at Carrow Road.
The clash with the Canaries, the reward for defeating Lincoln City 2-0 at Leigh Sports Village with a pair of Dillon Hoogewerf goals, will be shown live on MUTV with kick-off at 19:00 GMT.
Priority is usually given to the FA Youth Cup due to the prestigious nature of the competition and our long association with the tournament.
