Erik ten Hag has delivered a set of five values he wishes his Manchester United players to abide by, according to reports.
The Dutchman, who was confirmed as United boss in April, is taking charge of his first campaign at Old Trafford and getting to know his squad.
The club are set to embark on a pre-season tour of Thailand and Australia later this month, ahead of the Premier League season kicking off in August.
Ten Hag has been getting to know his players at the team's Carrington training base and is beginning to implement his own technics and methods.
A strict disciplinarian, the 52-year-old has now laid down a set of rules he expects each of his players to abide by.
According to the Daily Mirror, they include the mantra that any player late to training or team meetings will be dropped without exception.
Drinking alcohol during a matchweek is also something that will be banned. This will essentially work as a blanket ban on alcohol across the season, with United regularly set to play twice a week due to European commitment.
One of the biggest changes will be to food. Ten Hag has banned players from adopting their own personal chefs and wants all players to use the canteen at Carrington as their main source for meals.
Ten Hag has sought to overhaul the menu available as one of his first moves, with fish and vegetables now more prominent at meal times.
The likes of Luke Shaw have publicly flaunted their hiring of private chefs in the past, something which has seen players able to commit to their own dietary choices.
The Dutchman is also wary of players keeping their weight in check and as a result BMIs will be checked on a weekly basis.
Finally, he has requested that all player grievances are run by him, instead of going to agents or other sources.
Indeed, dressing room leaks were one of the main bug bears of previous bosses Ole Gunnar Solskjaer and interim head coach Ralf Rangnick, and they are something Ten Hag is hoping to eradicate from United.
Ten Hag has already been hit with his first major challenge at United, with Cristiano Ronaldo pushing for a move away.
Ronaldo was due to return to training this week, but was given leave of absence on Monday for family reasons.
However, the Portuguese star has still not shown, and it is now unlcear if he will even join the squad on their pre-season tour.
