Cristiano Ronaldo's superhuman jump was analysed by scientists back in 2011 and the findings were simply sensational.
The five-time Ballon d'Or winner produced another outrageous leap to score a stunning header in the 2-2 draw with Roma, displaying incredible hang-time to bag his second goal at the Stadio Olimpico.
It's a feature of Ronaldo's game and one that makes him almost unstoppable for defenders to deal with when the delivery is right, but just how does he defy gravity so regularly on the pitch?
During a series of biomechanic tests on the forward at the University of Chichester in 2011, with the whole thing captured in the in-depth Cristiano Ronaldo: Tested to the Limit documentary - it emerged that Ronaldo is able to jump higher than an average NBA player.
Able to generate 5G of G-force on take-off and helped by a thigh circumference of 62cm, he can reach heights of 44 cm from a standing start and 78 cm when he has a run-up - 7cm more than the average basketballer.
He also recorded a force of five times his body weight. Forget 'Air Jordan', it's all about 'Air Cristiano'.
It's no surprise that he continues to score the most insane leaping headers. In December, Ronaldo rose a ridiculous 2.56m in the air and got 1.5 seconds of airtime before meeting Alex Sandro's cross to score against Sampdoria.
It prompted manager Claudio Ranieri to compare him to an NBA player, saying: "Ronaldo did something that you see in the NBA (National Basketball Association), he was up in the air for an hour and a half.
"There's nothing you can say about it, you can only congratulate him and move on."
