Cristiano Ronaldo's legacy for both club and country is shining bright on his 40th birthday. To celebrate the superstar's birthday, the world is looking back at Ronaldo's one-of-a-kind career that started when he was just a teenager in Portugal.

Cristiano Ronaldo celebrated his 40th birthday on Wednesday with no signs of slowing down his majestic career.

Despite playing outside Europe at Al-Nassr in the Saudi Pro League, Ronaldo, the highest-paid footballer in the world, is "quite possibly the most famous person in the world", too. His star status is so supreme, that when he does finally hang up his boots, he will surely find ways "not just to sustain his fame but to expand it".
