Ronaldo Luis Nazario de Lima, commonly known as Ronaldo or Brazilian Ronaldo, is widely regarded as one of football's greatest ever players.
And today (September 18) he celebrates his 42nd birthday.
It's been eight years since the Brazil legend retired from professional football and we're yet to see another striker quite like him.
Fast and strong yet elegant and quick with his feet, Ronaldo was a defender's nightmare and scored all kinds of goals throughout his career.
At international level for Brazil he was prolific, too, scoring 62 goals in 98 games, winning the FIFA World Cup twice and the Copa America twice.
And let's not forget the individual accolades, which include two Ballon d'Ors, three FIFA World Player of the Year awards and one European Golden Shoe.
