Simeone says his time with Lazio convinced him to go for a coaching career.
"I was 27 or 28 years old when I really decided that I would become a coach," said Simeone.
"I remember I was returning home after training - I played for Lazio then - and pretended to have to drive a training session. I told myself: 'Let's work it out'. Do you know how children use their imagination when they play?
"I did the same thing as an adult, playing as a coach. I used my team and I imagined taking part in the training. I figured out the next game and planned everything I needed: in the end I was overwhelmed by sheets of paper covered with drawings and annotations."
