“I am an old man now, I am 36,” he told reporters at a press conference in New York.
“I am no longer 26 like I once was, and I am looking at what I can do to mark an end to my career. The plan is to play one more year.
While he gave few clues on what the future might hold, Ronaldinho affirmed that he may well be entering the music world.
“I am immersed in new projects, related to music and football which are, as you know, my two passions,” he said.
“I am looking at new things that I have always liked and we will see what we will do this year.”
