The 22-year-old international moved to PSG last year from Gremio, after a prolonged transfer which Fifa had to resolve.
However, the young Samba star has failed to settle in the French capital and despite being in good form recently he admits that he could leave.
"The present situation in PSG is not the one I imagined before I came," he said.
"We are not at our best, but life still goes on. When I came here, I thought we could win Le Championnat. But it won't be the case.
"So we have to think about what didn't work and prepare next season. You know I love to be here. Perhaps I could even stay ten years! But in a career, you can never know what will happen. So let's say I think I will be here next season, but we will have to see."
Ronaldinho, like a vast array of PSG's squad is hoping that the club qualify for the Champions League, otherwise the financially stricken outfit could be forced to sell a number of players.
