Palmero have attempted to price Europe's elite out of the market for star turn Javier Pastore by demanding €60 million for his transfer.
The 21-year-old has been making waves in Serie A this season and has been fetching interest from La Liga duo Barcelona and Real Madrid.
But with the pair never afraid to spend big in the transfer market, and Chelsea, Manchester City and Manchester United all backed by wealthy foreign owners, it is yet unknown whether Palermo's latest valuation of the player will see their attention turn elsewhere.
"Pastore is worth from €60 million [£52.85 million] going upwards," Palermo president Maurizio Zamparini told Radio Radio.
Chelsea, City and United have all been tracking the forward, and at different stages have been the front-runners for his signature.
With Didier Drogba, Carlos Tevez and Dimitar Berbatov all linked with moves away from Chelsea, City and United respectively, the three Premier League sides could all make a case for requiring Pastore's services.
The Argentine marksman is currently trying to help Palermo qualify for the Coppa Italia final, where they go into the home leg of their semi-final as favourites after drawing with AC Milan at the San Siro, a game where Pastore showed his class with a goal and an assist.
