Real Madrid coach Zinedine Zidane admits a lifestyle change was key to his success as a player.
After joining Cannes at the age of 17, Zidane changed his lifestyle in order to get to the top of the game.
"I slept well, I wasn't an idiot going around bars, I only drank water and did stretches," he told Otro.
"I put everything into becoming the best player possible, I had to do it at all costs. This is how I could make my parents happy, because it was my life, but I also did it to make them proud.
"To make yourself known, and then play, you had to be good, not like today. First you had to show that you were different to everyone else, because at the time there were a limited number of players - only one or two youngsters per team.
"Today it's all changed, it goes much quicker, and as for the players, they're no longer afraid of making mistakes."
