Ronaldinho has denied speculation in the Spanish press he is considering retiring from football at the end of the season.
The Brazilian star has not featured in the Rossoneri's last two games and has yet to find the back of the net after three appearances with the Serie A giants this campaign.
"I have never considered the possibility of retiring from football," said the 29-year-old on his official website, www.ronaldinhogaucho.com.
"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."
The two-times winner of the FIFA World Player of the Year award joined Milan from Barcelona last year, but he has failed to make an impact at the San Siro.
Milan owner Silvio Berlusconi had hoped that after selling Kaka to Real Madrid this summer, Ronaldinho would rediscover some form.
Rossonero 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 the Rossoneri until June 2011.
