Posting a black and white image of himself wearing the famous "I belong to Jesus" t-shirt he sported in the Champions League final against Liverpool, Kaka issued a statement reflecting on his career. He was part of the Brazil squad that lifted the global trophy in 2002.
Kaka, who played for Brazil, AC Milan and Real Madrid, told Brazil's Globo TV on Sunday that "my last word is that the cycle of my career as a player ends here".
He also added that he might continue taking part in the football world: "I will continue in football but in a different role".
The 2007 Ballon d'Or victor captioned his post with the message, "Father, It was much more than I could ever imagined". Thank you and now I'm ready for the next journey. Reports circulated around two specific offers: a return to his first love Sao Paolo for a one-year contract and another non-playing role as club director at AC Milan.
A graceful midfielder, Kaka won 92 caps for Brazil, scoring 29 goals and featuring at three World Cups. However, in the same transfer window Real Madrid broke the world record by signing Cristiano Ronaldo.
It was while at Milan that Kaka picked up the Ballon d'Or, awarded annually to the world's best player.
Having struggled with a series of knee injuries, Kaka returned to Milan for one season in 2013 before leaving for Orlando the following year. He is renowned for strong mazy dribbles and creativity on the pitch, which helps to provide opportunities to score.
