Kaka has left open the possibility of remaining at Sao Paulo after his loan contract expires in December.
The 32-year-old former Real Madrid and AC Milan playmaker is due to join new Major League Soccer franchise Orlando City in January, reports Xinhua.
But he refused to rule out an extension to the current deal with his original club, where he returned in July after 11 years in Europe.
"The time to talk will be the end of the season, not now," Kaka told Folha de S.Paulo. "Right now I am only focused on the present."
