Ricardo Izecson dos Santos Leite (born 22 April 1982), commonly known as Kaká, is a Brazilian football midfielder who currently plays for Real Madrid and the Brazilian national team.
He is widely considered as one of the best footballers of his generation, often drawing comparisons in style and ability to other great footballers as Michel Platini, Sócrates, Zico, and Pelé. His footballing style is unique as he has the technique of a Brazilian and the physical qualities of a European.
Kaká started his footballing career at the age of eight when he began playing for a local club called "Alphaville". By then, he also played tennis and it was not until he moved on to São Paulo FC and signed his first professional contract with the club at the age of 15 that he chose to focus on football.
He was the recipient of both the Ballon d'Or and FIFA World Player of the Year awards in 2007. Besides his contributions on the pitch, Kaká is also famous for his humanitarian works and work against poverty.
In 2004, by the time of his appointment, he became the youngest Ambassador of the UNICEF food program.
