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