All of Juventus celebrate Cristiano Ronaldo's birthday. His fitness trainer at the time of Real Madrid, Giovanni Mauri, spoke about his athleticism and his future in a long interview.
Tuttosport interviewed Giovanni Mauri (who is one of Carlo Ancelotti's trusted staff) to talk about Cristiano Ronaldo's physical level:
"Would the renewal lead him to play up to 38 years old? I have coached several greats, such as Maldini and Costacurta. Ibrahimovic also at PSG and I was sure he would play until he was 40. They are all athletes who have great flexibility in addition to their power."
Mauri goes on with his analysis: “Ibrahimovic has the mobility of a dancer despite weighing almost one hundred kilos. They are like thoroughbred horses: it seems a contradiction but it is the secret of their speed. Cristiano Ronaldo is part of this category and can certainly remain at high levels up to 40 years."
