Manchester United manager Jose Mourinho says that the club is lacking in good players aged 20 and 21.

Mourinho has used academy graduates throughout the club’s preseason tour of the US, including Tahith Chong, Angel Gomes and James Garner.

But with the club’s Under-23 squad suffering relegation last season, Mourinho says that he had no choice but to go younger.

And he believes that the level of quality is “not good” in the next age group off the conveyor belt.

“We have just a few players here, lots of kids, our kids are really, really young,” Mourinho said.

“That’s because the team of older ones, the under-23’s, the team was relegated.

“The team went to the second division, so the quality was not good so we prefer to bring kids.

“The good young players are too young. We don’t have good players of 20, 21, like for example Real Madrid have, our good players are young, they are 16, 17.

“We are going to make good players from our youth team again when they grow older because I repeat, our under 23’s were relegated.”
