Tottenham Hotspur boss Harry Redknapp had previously revealed his interest in bringing the former Manchester United forward to White Hart Lane, with the striker's price tag proving a significant stumbling block.
And it is the Serie A club who are currently locked in talks with the Spanish side over a proposed deal to take Rossi to Italy.
However, Pastorello claims the Old Lady are yet to meet Villarreal’s asking price for the 24-year-old.
“Villarreal await the right offer, one that reflects the value of Giuseppe,” Pastorello told Gazzetta dello Sport.
“There's a lot of money at stake and I believe the asking price is correct considering the value of the player. It is not disproportionate.”
Juventus were reportedly keen on signing Atletico Madrid’s Sergio Aguero, yet a deal for Rossi appears more feasible to the Italian giants.
“Juventus and Villarreal are discussing the financial figures and I await developments,” added Pastorello.
“But if the right offer does not arrive, I am in agreement with the club [Villarreal] that he will stay.
“I have spoken to Giuseppe and he is calm. He is not anxious.”
Rossi, who has a buy-out clause of €33 million, enjoyed a superb campaign in Spain last season, scoring 32 goals in all competitions.
