One of Ronaldo's major secrets is sleep, Cristiano sleeps five times a day.

Nick Littleales worked with Ronaldo during his time at Real Madrid and told of The Independent how Portuguese prepares for matches. “Randaldo sleeps in the position of the fetus and does it several times a day, but no more than an hour and a half.

Whoever's ever worked with Ronaldo knows that if you discuss the corner of the room, he'll come out and ask what you're talking about. I was invited to Real Madrid when Carlo Anceplott became a coach in 2013. One day I was standing on the edge of the field talking to the staff when Ronaldo ran.

He trained all day and expected him to run directly into the dressing rooms to take a shower and rest, but he asked what we were discussing. He was interested in what I was trying to do, what my plan was, because as a sportsman, he always invested in himself. From what I learned during my work with him, Ronaldo is not interested in fashion diets, not interested in cheating. The only thing he cares about is if it works specifically?

It's interesting that Littles also worked with the legendary United United States coach, Sir Alex Ferguson, but that was after Ronaldo left the club in 2009.
