United have included an academy player in every matchday squad since October 1937 and Mourinho is intent on extending that run.
"I don't want to be the one that breaks that and I think the next United manager - it doesn’t matter when he comes - should also try not to break it,"
Mourinho told The Mirror. "It is more difficult now than it was before, but I think it is good.
"I feel it like a way to keep a certain identity of the club. To keep that identity means, basically, we should bring a new player from the academy every season. You can bring someone to play 10 minutes, then the player disappears and then you can say, ‘Oh, 40 players have their debut with me.' But none of them are important.
"I think what is happening with Lingard and Rashford is now happening with Scott McTominay, because he is not going to leave the club any more. To follow a certain pathway is important. I am doing it with McTominay.
"Mr. Van Gaal had the start of Rashford, I am having it with Scott McTominay and, next year, there should be more."
