Palermo President Maurizio Zamparini has revealed the latest transfer status regarding Javier Pastore and Abel Hernandez.
Speaking to Voce Giallorossa, the Rosanero chief said that he was only willing to let go of one of his young talents.
"Hernandez is absolutely not for sale and that won't change no matter what offers are made, even those of over €20m," he stated.
"Pastore, meanwhile, could leave, but the starting price for negotiations is €50m. He is one of the few world class players who are left in Italy."
The Uruguayan Hernandez, born in August 1990, is a striker who has been with the Sicilian club since his 2009 move from Penarol.
Roma had been paired with a possible swoop for the talented youngster.
Pastore, on the other hand, is an Argentine international midfielder who is being monitored by Europe's top clubs.
He was signed in 2009 after a season with Huracan for a fee believed to be around €5m.
