Woe betide any Manchester United player who reports late now that Erik ten Hag has been confirmed as the new boss at Old Trafford.
The Dutch coach is a stickler for punctuality. If a press conference is scheduled to begin at midday, the door will open at 11.59 and the first question asked will be 12 on the dot.
If a line of questioning becomes too persistent - and the Dutch press have discovered this recently in tetchy exchanges over his new job - then Ten Hag will raise his sleeve and glance at his watch.
