Javier Pastore's agent has confirmed he is set to fetch Palermo no less than 50million euros.
That was the valuation Palermo made at the start of the summer as they expected a wealth of interest in the highly-rated 22-year-old playmaker.
Chelsea, Real Madrid and Barcelona are all in the race to sign the Argentina international and Palermo president Maurizio Zamparini confirmed on Wednesday that there was only a 10 per cent chance he would remain with the Sicilian side as an unnamed club had made a €50m bid (£45.1m).
Pastore's agent Marcelo Simonian backed up Zamparini's claim, so the player is set to leave Palermo this summer with their asking price having been met.
But Simonian has left the door open for a bidding war, saying that one of his other suitors are welcome to step in with a bigger bid.
"It's true, there is someone that wants him at that price," he told Gazzetta dello Sport.
"This is the basis, hence, the price will absolutely not be lowered.
"If anyone wants him they can contact us. Pastore is calm and never asks me about the (transfer) market, we speak about other things."
Pastore joined Palermo from Huracan in 2009 for €19m (£17.1m). He was their leading Serie A scorer last season with 11 goals and is under contract at the Stadio Renzo Barbera until June 2015.
