One of the biggest decisions Jose Mourinho has made at Manchester United was one that saw him pay £89 million for Paul Pogba.

The Portuguese clearly felt that United needed a marquee signing and while Zlatan Ibrahimovic also arrived in the summer transfer window, Pogba was the one that really got fans out of their seats.

The Frenchman is a rising star and was attracting interest from Real Madrid. To beat Los Blancos to his signing, as well as setting the record for most-expensive transfer in football history, was a real statement.

Yet it’s not a secret that Mourinho prefers managing mature players. The 54-year-old is very often criticised for his track record when it comes to developing young players, and Marcus Rashford is finding out just how hard it is to impress the United boss.

Mourinho has expanded somewhat on his opinion of today’s young stars. He didn’t hold back, either, saying most 23-year-olds in football today are “brats” and that it’s rare to find a mature young player like Frank Lampard was.

“I have had to adapt to a new world and what young players are like now,” Mourinho said in an interview with France Football, via the Independent.

“I had to understand the difference between working with a boy like Frank Lampard who, at the age of 23, was already a man – who thought football, work, professionalism – and the new boys today, who at the age of 23 are kids.

“Today I call them ‘boys’ and not ‘men’. Because I think that they are brats and that everything that surrounds them does not help them in their life nor in my work. I had to adjust to all of that.”

"Ten years ago, no player had a mobile phone in the dressing room. That is no longer the case. But you have to go with it, because if you fight that you are bringing about conflict and you risk putting yourself in the stone age.”

Pogba was 23 when he joined United

It’s interesting to note that Pogba was 23 when Mourinho signed him. Does the United manager think the Frenchman is a brat?

We'd love to know what he made of Pogba's dance routine with Jesse Lingard, something that never would have been seen in Roy Keane's days.

Mourinho knows all about the social media struggle

The former Chelsea boss is a father himself, so he’s fully aware of how influential social media is today.

“I admit that having a son and a daughter at that sort of age has helped me to understand the way they function and what the world is today,” he added.

“If you stop a player from doing something, even something a little stupid, on social media, you are going against nature.”
