Ronaldinho says he was disappointed not to play in the derby, but insists that he doesn't intend to leave the club.
The 30-year-old Brazil international has lost his place in the team after Massimiliano Allegri decided upon a tactical shift.
"I wasn't happy [on Sunday]," Ronaldinho said. "You can't be happy when you don't play an important game like the derby.
"But I look at the League table and I am happy. Yes, happy.
"Milan are top: they have everything to win the Scudetto. I knew it from the first day of training. I understood that there was a new atmosphere.
"Now the opponents will also have understood."
When asked about his future, Ronaldinho said: "I repeat for the last time. I don't have any intention of leaving Milan.
"Actually I will say more: the victories that I will conquer with the Rossoneri will give me the push to follow my life's dream: that of playing at the 2014 World Cup in Brazil.
"Take my name off all the transfer market stories. I am happy at Milan. Happy."
