It's often said that Cristiano Ronaldo is from another planet, and now stats have emerged that would corroborate such a theory. The Portuguese forward has just completed his medical at new club Juventus, with doctors left stunned by the 33-year-old's physical condition.

Spanish football newspaper Diario AS reports that Ronaldo, who recently joined the Italian champions for a fee reported to be worth around $140 million, has the physical capacity of a 20-year-old. According to his medical results, Ronaldo has just 7 percent body fat, around 3 percent less than the average professional footballer, while his muscle mass stands at 50 percent, around 4 percent more than the average player. At the World Cup in Russia, Ronaldo hit a top speed of 21.1mph, making him the joint-fastest player at the tournament. Croatia's Ante Rebić, nearly a decade his junior at 24, was the only player who could match him.

A teetotal fitness obsessive, Ronaldo follows a strict regimen to stay in peak condition. He is said to go swimming after every match and has a $52,000 cryotherapy treatment chamber installed at home to treat his muscles for fatigue. Legend once had it that the former Real Madrid icon does 3,000 sit-ups per day, although he later denied the rumor.
