Pastore has long been linked with a move away from Palermo and is expected to leave the club this summer.
"At the moment we are waiting and will make a decision in the next few days, after tomorrow's Europa League game against Thun," Sogliano told RMC radio.
"We have received interesting offers from Paris Saint-Germain and Chelsea."
"It's true, I have a good rapport with Palermo President Maurizio Zamparini and everyone would like a player like Pastore," confessed PSG director Leonardo.
"We are working on possibilities and want to bring players who above all believe in our project.
"At the moment our priority is to sign a new goalkeeper, as we are missing someone in that role."
