Cristiano Ronaldo doesn't jump to win his headers, he flies.

The Juventus superstar proved that to the world all over again when he scored against Sampdoria earlier in the month, rising an astonishing 2.56 metres to score past Emil Audero.

Even Ronaldo himself was shocked to learn about the height and his manager Maurizio Sarri remarked: "When Ronaldo scored I thought the same as the Dybala one - 'f***, wow.

"The [Ronaldo] one, I think the amount of time he spent in the air before the header was incredibly long – a wonderful, physical and technical action."

It wasn't the first time that Ronaldo leapt to new altitudes for a goal, bringing back memories of his 2013 strike against Manchester United and his opener in the 2008 Champions League final.

'AirRonaldo' goes viral

And it seems the 34-year-old is just as aware of the recent 'AirRonaldo' trend as football fans, because he's decided to ride the wave and pass on some of his knowledge.

However, Ronaldo hasn't revealed his secrets to any old average joe, but has instead given a jumping masterclass to tennis superstar Novak Djokovic.

The 16-time Grand Slam winner made an appearance on Ronaldo's Instagram on Friday morning, listening to his fellow sports star on how to jump high enough to reach a gym rope.

Ronaldo teaches Djokovic

Ronaldo captioned the post: "Teaching @djokernole how to jump!!😅🤪💪🏽 Was a pleasure to see you and train with you my friend!!" and it's already amassed five million 'likes.'

Wow, even a fellow elite athlete can't jump anywhere near as highly as Ronaldo.

An alternate angle shows Ronaldo comfortably reaching the target with his head, while Djokovic - who still needs spring in his boots when serving - also touched a slackened part of the rope.

Ronaldo could be seen advising Djokovic to start 'slowly', only use a single leg for take-off and to really lift his knee during the jump for extra air time. 

GIVEMESPORT's Kobe Tong says

When it comes to football, Ronaldo is the ultimate athlete.

Suggestions that he could give professional high-jumpers a run for their money were complete hyperbole, but his air time resembles that of an NBA player as opposed to a footballer.

And as Ronaldo has become more of a poacher over the last half-decade, it's helped him score some more smash-and-grab goals to keep his scoring tallies amongst the world's best.

Just when you think the Portuguese has reached his limited, he quite literally raises his game to new heights. Sorry, Novak, even you can't compete with him.
