The star's brother and agent, Assis, said: "Ronaldinho is happy here. The crowd has been with us and encouraging every day - and although last year we were not champions, the club has done a great job in recent years.
"The players are at a high level and everyone is improving little by little and day by day. Ronnie has no date to leave, the idea has always been to stay together and he's never thought of a transfer.
"The most important thing is the passion and love of the people and that's not something you forget about overnight. "
Reflecting on his brother's performance at Celtic last week, Assis said: "Ronnie played one of his best games in the last two years, but the problem is not him. To succeed, you need your teammates to be playing well also. Not only Ronaldinho.
"Everyone has been questioned in the past year because this is a great club and always must win. The press creates situations, but our idea is to continue here and we have said it a thousand times. And the board has said the same thing, but it seems that nobody in the press wants to believe it."
