As many as 15 first-team players are expected to join Erik ten Hag in his first-ever training session at Carrington on Monday, reports the Manchester Evening News.
Prior to that, the MEN claims some Manchester United players have reported to the training base this Saturday to complete their medicals.
Those who are not on international duty begin training on Monday.
That includes the following players - David de Gea, Dean Henderson, Tom Heaton, Aaron Wan-Bissaka, Victor Lindelof, Eric Bailly, Phil Jones, Axel Tuanzebe, Brandon Williams, Luke Shaw, Donny van de Beek, Amad, Jadon Sancho, Anthony Martial and Marcus Rashford.
Those taking part in international games this June will receive a three-week break and are scheduled to report for pre-season training on July 4.
Both Lindelof and Bailly were selected for their respective countries but pulled out through injuries.
Meanwhile, Deano is expected to complete some formalities before being whisked away to Nottingham Forest for his season-long loan.
