Rio de Janeiro, July 25 - Kaka is set to make his long awaited return for Sao Paulo Sunday, 11 years after his last appearance for the Brazilian club.
The 32-year-old, who joined his former side on a six-month loan earlier this month, trained with Muricy Ramalho's first-team squad Thursday, Xinhua reported.
According to news portal Globoesporte, the 2007 FIFA World Player of the Year is certain to start against Goias in Brazil's Serie A championship.
Sao Paulo striker Alan Kardec described the prospect of playing alongside the former Real Madrid and AC Milan playmaker as a dream come true.
He is an idol for all Brazilians for everything he has won, where he has played and the person that he is, Kardec told a press conference.
Kaka began his career at Sao Paulo and made 59 first-team appearances for the Tricolour before moving to AC Milan in August 2003.
After a four-year spell at Real Madrid, Kaka returned to AC Milan last year.
He left the San Siro by mutual consent in June and a month later signed with Orlando City, from where he has been loaned.
