Pastore joined PSG from Italian side Palermo and has recently been strongly linked with a return to Italy.
But Pastore's agent, Marcelo Simonian, insists his client is happy in Paris.
"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."
