The 24-year-old has been linked with a move to the Giallorossi, and although he insists that he is happy in Paris, he would seriously consider a transfer if the Italian side submitted an offer to his agent.
"I am happy here and, as I've said, I don't want to leave," he told Fox Sports.
"Roma? There are teams that have spoken with the club and with my agent. Roma are doing very well and have a strong squad.
"If they were to call me then I'd have to see what happens. But at the moment I am happy in Paris."
Argentine international Pastore joined PSG from Palermo in August 2011.
