United will get their first glimpse of the Dutchman's managerial methods at Carrington when the squad returns to training on June 27.
In an effort to prioritise on-ball drills during the opening sessions, Ten Hag has told his staff to trim the grass to exactly 15mm, so that the players can quickly get up to speed with his passing demands.
The Mirror says the former Ajax coach will measure the overall fitness of his players during the first two days of training but plans to put their stamina to the test with passing drills rather than fitness exercises.
Ten Hag is also keen to foster a positive team spirit in the Red Devils dressing room and as a result has insisted that the squad must eat together and socialise after training.
Old Trafford legend Sir Alex Ferguson made similar demands during his 26-year tenure at the club, but this culture has since evaporated within the camp.
