The Argentina international is set to leave the Sicilian outfit this summer with several top European clubs, including Barcelona, Chelsea and Manchester City in the race to acquire the 22-year-old's services.
"There are five clubs keen on Pastore and one of them is Italian," said Zamparini to Stadionews. "It's not Napoli or Juventus."
The highly-rated playmaker, who is currently competing at the Copa America, joined Palermo in 2009 from Huracan for 19million euros and was the team's leading scorer in Serie A last season with 11 goals.
Pastore is valued at 50m euros and is under contract with Palermo until June 2015.
"There is a 99% chance that Pastore will leave," said Zamparini.
"But I think that without him the team will be able to fight to qualify for the Champions League."
