Reports in the Italian press have suggested the Brazilian is being linked with a move to fellow Serie A outfit Sampdoria and German side Bayer Leverkusen.
Alessandro Lucci has dismissed all reports linking his client with a move though, saying he is very happy with the Rossoneri.
"Serginho will remain at Milan," Lucci told skysports.com. "He is not going anyhere.
"Serginho has no intention of leaving Milan because he likes it here. These stories are just speculation."
Reports have also suggested the left-sided star could be used as bait for any future deal the European champions indulge in to bring in a player, but Lucci says the South American will only move on if it is to one of Europe's elite, naming Juventus and Real Madrid as examples.
"If Milan have the intention to use him as a pawn in an exchange for a player from a big team, for example, Juve or Real, then he may consider the possibility," added Lucci.
"But he wants to stay with the Rossoneri," he concluded.
