Manchester United boss Ole Gunnar Solskjaer is upset seeing his players ignore his demands for better dress standards.
The Sun says Solskjaer has tried to restore some of the club's former culture since replacing Jose Mourinho a year ago.
Sir Alex Ferguson ordered his stars to dress smart before games and Ole, who became a club hero under the legendary boss, has followed suit.
But it is reported that the boss and his staff have been angered by some players wearing extra items - mainly hats and accessories - given to them by sponsors.
The report does not name any players in particular.
