The Spanish press recently claimed Barcelona had already started negotiations with AC Milan to acquire the 27-year-old defender.
The Brazil international is also a reported target of Manchester City, Chelsea and Paris St Germain.
"I can assure everyone that I have not been contacted by Barcelona or any other club," Silva's agent Paulo Tonietto told www.calciomercato.it.
"Milan have not notified me of any update. There are just rumours and there is no truth in it."
The Rossoneri have reiterated they have no intention to part company with Silva, who is under contract until June 2016.
Silva joined Milan in 2009 from Fluminense after previous unsuccessful spells in Europe with Porto and Dinamo Moscow.
