Corinthians have expressed interest in taking Pato on-loan next season.
But the young striker said: "Some Brazilian players remain in Europe for about 10 to 12 years. I would be 27 if I return after 10 years here.
"Who knows whether I will then return to Brazil. You never know what will happen in the future.
"I can only thank the clubs that have approached my agent. I just have to do my thing on the pitch."
