The Holland international was stunned to be told that he wouldn’t be part of Louis Van Gaal’s 18 for the Wembley clash with Crystal Palace.
He was said to be angered by the news after previously being a squad regular this season.
And the fact that the man brought him to the club for £25m, and previously managed him at the 2014 World Cup, was prepared to leave him out of arguably the most important match of his two-year reign speaks volumes.
The United players reported to the club’s Carrington base yesterday before training and travelling to Stockport, where they got the train to London.
But Depay left in his car and it is thought he will travel to Wembley today with club officials.
