The Portuguese coach left los Blancos for Chelsea last summer after three years in charge of the Santiago Bernabeu side and he was not impressed by the attitude shown by his players during his time at the club.
"Lots of times at Real Madrid, the players would be queuing in front of the mirror before the game while the referee waited for them in the tunnel," Mourinho told Esquire. "But that’s how society is now. Young people care a lot about this: they are 20-something and I am 51 and if I want to work with kids I have to understand their world.
"I’m a manager since 2000, so I’m in my second generation of players. What I feel is that before, players were trying to make money during their career, be rich at the end of their career. But, in this moment, the people who surround them try to make them rich before they start their career."
Mourinho won one La Liga title, the Copa del Rey and a Supercopa de Espana during his three years at Madrid.
