Ole Gunnar Solskjaer has ordered Manchester United's players to wear their official club suits to all matches as he continues to impose his ethos on the squad.
The United stars are still allowed to travel in their club tracksuits, as they did on the train to Watford for Sunday's 1-0 win over Tottenham.
But when Solskjaer and his players arrived at Wembley 24 hours later, they were more formally dressed in suit and tie on the instructions of their caretaker manager.
A smarter dress code is just one of the ground rules Solskjaer has borrowed from Sir Alex Ferguson, who was seen at United's Carrington training ground again on Saturday before the squad left for London.
The 45-year-old, who has done the same at Molde, informed the United players of the new regulation on their warm-weather training break last week.
'In Dubai we had time get the tactics right and some principles laid down,' he said before the win over Spurs.
It's understood that Solskjaer also used the trip to assess his squad more closely away from the training pitch. Although the players weren't given a curfew, it was noted by the coaching team that some took advantage of the relaxed conditions more than others.
The break, described by Solskjaer as a 'mini pre-season' similar to those introduced by Ferguson, appeared to pay off as United won for the sixth game in a row under him to go level on points with fifth-placed Arsenal.
The squad stayed at the Wembley Hilton, just yards from the national stadium, on Saturday night after experiencing travel problems in London in recent years.
