Former Manchester City boss Stuart Pearce has questioned Erik ten Hag's new rules for his Manchester United squad.
The former Ajax boss has introduced new values at the club since arriving, which include any player late to training or team meetings being dropped and banning players from using their own personal chefs.
Pearce told talkSPORT: "If you've set those five rules up, they must all be run past him and then he has to deal with every little problem that they throw up.
"Let's take the diet for example. A lot of these players employ their own chefs away from football. You can't police that.
"They do it for the right reasons, and for the different foods that they have culturally around the world.
"By putting something like that individual rule in place, you've got to police it! And how do you police it?"
On Ten Hag's rule on lateness, Pearce added: "Being late is common sense. You wait until he drives around and gets stuck in traffic on the M60!
"If you're a first-team player and you get stuck in a bit of traffic on your way to training and you're dropped, would you say 'fine, they're the rules, what can I do about it?'
"It is unpoliceable at times. Common sense has got to play a fair part. You're just asking for trouble as a manager."
