The likes of Chelsea, Inter Milan and AC Milan are said to be keen on the Palermo star.
He is currently away on international duty with Argentina at the Copa America, but that has done little to curb the speculation regarding his future.
It is claimed that big-money offers are being readied across Europe, with it expected to be only a matter of time before a bidding war begins.
There is, however, no sign of a mass scramble beginning any time soon, as Pastore's representative insists he is yet to be contacted by any of those clubs leading the chase.
Marcelo Simonian said: "President Zamparini has set his price at €50m (?44million), a valuation with which I totally agree.
"We both know Pastore's potential, so we are not in a hurry. And Javier is not anxious to leave either.
"He could remain for another season in Palermo and be happy.
"In any case, I can say that there has been no contact with Inter, AC Milan and Chelsea."
