Marcos Cafu and Serginho have confirmed they're leaving AC Milan at the end of the season.
"I don't know if I'll play on in Brazil," he said. "All I know is that my last game for Milan is on Sunday and I don't know whether I'll get to play or not.
"I am ready to take on such an important task. Carlo Ancelotti will be able to count on me on all fronts.
"It's not easy to say goodbye to the fans who have welcomed me in a fantastic manner, I hope I haven't let anyone down. I will continue, however, to support Milan."
It will also be an emotional day for Cafu's compatriot Serginho, who joined the club in 1999 and is also heading for the exit.
"After my back problems, I haven't been able to get back to peak fitness, which is why I think the time is right to leave," the 36-year-old said.
"I came to Milan in the summer of 1999 along with Gennaro Gattuso and Andriy Shevchenko when I was 27 and I have spent nine splendid years for which I thank the club and the fans.
"I have managed to find a piece of Brazil in Italy and it has been stupendous.
"Having come here to complete a mission, today I can calmly accept that my career is over.
"Sunday evening will be difficult because San Siro has become my home, but I am happy with everything I have done for this club."
