The Portugal international has enjoyed an incredibly successful career at the highest level since his arrival on the scene at Sporting Lisbon, giving supporters many unforgettable moments.

In 2008, Ronaldo stepped up to take a free-kick in a Premier League match against Portsmouth, and scored arguably one of the most famous goals of his career. Using his trademark knuckleball-style technique, his strike went like a bullet into the back of the net from 30 yards.

Opposition goalkeeper David James was rooted to the spot, hardly moving before the ball entered the goal. Players around the world have tried adopting Ronaldo's free-kick technique, with that goal seen as the ultimate example of when it works.

A year later, he stepped up similarly against Arsenal, but this time it was from a wider angle and even further out. Although Manuel Almunia moved towards it, the sheer power of Ronaldo's effort had him beaten all ends up.

His strike from long distance against FC Porto in the UEFA Champions League is also among the best goals of his career, as is his special backheel effort for Real against Rayo Vallecano in 2012.

After the ball fell to him in the box with his back facing the goal, Ronaldo confidently hit the ball with the back of his heel, and sprinted off to celebrate with his teammates who were equally as impressed as the Portuguese himself.

In 2018, he shocked supporters so much that even rival fans stood up to applaud. This happened in a crunch Champions League match against Juventus, whom he went on to join a few months later, and it remains one of the greatest bicycle-kick goals in the competition's history.
