Marcus Rashford reported back to training at Carrington on Monday and Tuesday despite being one of five players given extended leave to secure moves away from Manchester United.
The club directive would also have kept Rashford away from Ruben Amorim, with whom he had fallen out before moving to Aston Villa on loan for the second half of last season.
The England international did not participate in team training with the rest of the Red Devils squad and instead completed an individual session.
Along with Alejandro Garnacho, Antony, Jadon Sancho and Tyrell Malacia, he still has access to the medical and rehab facilities at Carrington if needed.
