Cristiano Ronaldo once again showed how much his heading technique has developed across his career after he scored two headers against Atlético Madrid in the Champions League earlier this week.
The Juventus ace was a brilliant winger during his days for Manchester United, but after he left the Red Devils for Real Madrid, the five-time Ballon d'Or winner continued to improve and became more and more deadly in the air.
Well, one former striker has decided to look into the 34-year-old Portuguese footballer's technique.
Tony Cascarino, who previously played for Gillingham, Millwall and Chelsea, believes that Ronaldo could be the best when it comes to heading the ball.
"The range of headers Ronaldo can score is extraordinary and he has worked so hard to reinvent himself from the tricky winger who made his name at Manchester United a decade ago," he wrote in his column for the Times.
"The 34-year-old Portuguese has taken heading to a new level and has mastered so many different types of header when most players are lucky to be good at one or two.
"I always thought the best aspect of my game was my heading and there were not many better than me in England while I was playing.
"But Ronaldo is a class above anyone who has ever played the game.
"I've tried to explain before about how there are as many different ways of heading a football as there are kicking one.
"You can head with the left side, the right side, the forehead, or the top of the head.
"Ronaldo's heading is like a perfect golf swing, everything is working in tandem and when it all clicks there is little you can do to stop him.
"His body shape has changed a lot over the years and he has clearly spent a lot of time working on his upper body strength.
"This allows him to lift himself into the air and get his body in the right position to head the ball.
"The strength of his thighs is also pivotal to the height of his leap. I had a very skinny body but had massive thighs, they were too big for my body.
"Ronaldo has thighs that look naturally big but he has done plenty of work to bulk them up and they play a key role in the explosiveness of his jumping."
It's some high praise for the former United and Madrid star, who has continued to showcase his incredible ability this season. In fact, one study recently found that he doesn't feel the pressure in big matches.
