Roma coach Jose Mourinho says he's changed since first entering the game.

Mourinho spoke of his time in football and reflected no how he's changed over the years.

He said, "We are paid to win. Athletes, not men, are paid to win. We are talking about high performance, and sometimes there are decisions in the management of a team that have something cruel about them, there is no time to let them mature, to let them grow…"

He highlighted how costly mistakes could be in the world of football and touched on the frustration that wasted talent causes.

“I am very clear about that. I try to help others and myself to be better. One thing that's hard for me to accept is the waste of talent, it's something that still after 30 years of football, is hard for me to accept.

He also said, “I perceive my evolution as a person by thinking about the fact that for many years I wanted to win for myself, whereas now I'm in a moment where I continue to want to win with the same intensity as before or even greater, but no longer for myself, but for players who have never won, I want to help them…

“I think much more of the ordinary fan who smiles because his team has won, of his week which will be better because his team has won. I'm still a “competition animal", so to speak, I still want to win as much or more than before, but before I focused on myself…"
