Kaká was one of the finest footballers of his generation, winning the Ballon d'Or title in 2007.
The Brazilian's finest years were spent at AC Milan where he won the UEFA Champions League before a big-money move to Real Madrid. His time in the Spanish capital didn't live up to the hype, with the elegant playmaker beset by injuries for most of his stay at the Bernabéu, but his legacy remains intact.
The UEFA Champions League official Twitter account has treated us to a video celebrating a special talent. Enjoy.
And here's his dream team. Quite a lineup.
Happy birthday Kaká!
