Mentally completely different. The dedication Ronaldo had to becoming the best in the world is fairly unique.
Ancelotti talking about Ronaldo
"He is a pleasure to manage," said Ancelotti. "We all know about the work he puts in to be so strong and his perfectionism on the training ground when it comes to technique.
"He also understands that a lot about being a top footballer, with the demands of the modern game, is about recovery. It is what you do in between the games that counts for so much. He would talk to our medical staff all the time, he would try to figure out what he needed.
"The boy lived for the game – everything else was built to fit around it. That meant his recovery times, what he ate, when he ate, his commercial commitments, even his private life. All of it was organised so that when he stepped on the pitch he would be at the absolute peak of his performance.
"No footballer can be 100 per cent fit every time he plays, but Ronaldo never got badly injured because he did so much of the prevention work that can help you avoid those sort of problems."
