The Italian defender has said that he will not join the Turin outfit at the end of the season, but conceded that he does not yet know what his future holds
The 36-year-old's current contract expires at the end of the 2011-12 campaign, and the Italian has yet to commit his future to the club.
Juventus are reportedly monitoring Nesta's situation, with Andrea Pirlo revealing last week that he discussed the possibility of a move to Turin with his former Milan team-mate.
The ex-Italy international says that he has not yet made a decision on his future, but insists that signing for Juve is out of the question.
"We will see about my future, I will decide what to do at the end of the season," Nesta told Milan Channel.
"I will surely not go to Juve, this is clear. Everything that has been written is not true. I do not have an agent and if someone wants me, they have to talk to me directly.
"No one has contacted me, I do not need to go to Juve, and they do not need me. There is no problem about this."
Nesta, who signed for Milan in 2002, has made 21 competitive appearances in 2011-12.
