Manchester United boss Jose Mourinho has had a pop at today's modern footballer.

Mourinho says he is working hard to keep up with the modern game's "brats" who lack the maturity of the likes of Chelsea legend Frank Lampard.

He told France Football: "I had to adapt to a new world. To what young players are now.

"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 who at the age of 23 are kids.

"Today I call them 'boys' 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 that. 10 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 put yourself in the stone age."
