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.
