Ronaldinho has denied speculation that he is considering retiring from football at the end of the season.
"I have never considered the possibility of retiring from football," said the 29-year-old on his official website. "The source of my happiness has always been to play football. I am happy at Milan and I will remain here until the end of my contract."
Ronaldinho joined Milan from Barcelona last year, but he has failed to make an impact to match his heyday at the Camp Nou. Brazilian radio station Jovem Pan reported that the midfielder had considered retiring from football during his last year at Barcelona, having been talked out of it by his brother and agent, Roberto de Assis.
Milan owner Silvio Berlusconi had expressed his hope that this season, after selling Kaka to Real Madrid this summer, Ronaldinho would rediscover some form.
Rossoneri coach Leonardo has not been impressed, however, and the player was not included in the 2-1 Champions League victory at Marseille last week, nor did the South American feature in the narrow triumph over Bologna at the weekend.
Ronaldinho is under contract with Milan until June 2011.
