The Serie A side have been strongly linked with the former Palermo man, with Napoli president Aurelio De Laurentiis revealing that as many as three new players could be signed in January.
However, the Argentine's representative, Marcelo Simonian, has said that there has been no contact with Napoli over a deal and insists that Pastore is "very happy" in France.
"Pastore loves Italy, but now he must think only about the present, not the past or the future," he told NapoliCalcioLive.com. "I do not think that a transfer to Naples is possible at this time.
"PSG's intention is to hold on to him, and furthermore, Javier wants to continue his career with a club that have always believed in him and treated him well.
"He is very happy in France, just as he was very happy in Italy. In addition, I have not had contact from anyone of late."
The 24-year-old joined PSG from Palermo in August 2011.
