In the recently concluded World Cup in Russia, Ronaldo registered the highest speed of the tournament when he clocked a top speed of 34km/h despite being 33 years old!
Cristiano Ronaldo has always been in great shape over the course of his career, particularly at Madrid. He literally worships his body and follows a strict diet regime to keep his body in shape. Since the career threatening injury he suffered in the Euro 2016 final, he has missed only 6 games owing to an injury.
Moreover, he has evolved his playing style quite considerably, now he stresses less on dribbling and more on his off the ball intelligence. Looking at his current fitness level, it is safe to say that Ronaldo can carry on for at least 2-3 seasons playing at the highest level, this will give him enough time to excel at Juventus.
