Palermo president Maurizio Zamparini has told Sky Sport Italia that those sides considering an approach for highly-rated forward Paulo Dybala will need to dig deep in order to get a deal over the line.
Premier League heavyweights Arsenal are among those to have been linked with the Argentine forward, with the Daily Star suggesting that Manchester United and Liverpool are also in the race.
They have, however, been told that the 21-year-old will not be leaving for anything less than 40 million euros (£31m).
Dybala has been on the books at Serie A side Palermo since 2012 and they intend to be handsomely rewarded if they are forced to part with a player they have helped to turn into one of Italian football’s most sought-after talents.
Zamparini told Sky Sport Italia: “(Franco) Vazquez will certainly renew his contract, but I’d have preferred for it to be sorted out six months ago.
“As for Dybala, so far offers for him have only come in obliquely, because they know how tough Zamparini can be.
“He is a world class player who is being compared to Javier Pastore, so his price-tag matches the skill: we’re talking €40m and upwards.”
Palermo offloaded Pastore to Paris St Germain in 2011 having helped another Argentine playmaker to shine on the European stage.
Dybala may soon be treading a similar path to his countryman after netting nine goals and providing four assists in the 2014/15 campaign.
Premier League sides would have no trouble bringing him to England as despite the fact that he is yet to appear for the land of his birth at international level, he holds dual citizenship and is eligible to represent Poland and Italy.
