Napoli rejected an offer from Atletico Madrid of €60million "plus two or three players" for Gonzalo Higuain, according to club president Aurelio De Laurentiis.
The Argentina international's future has been the subject of intense speculation in recent weeks, with Atletico, Juventus and Arsenal all heavily linked with an interest.
Juve held talks with their Serie A rivals over the striker this week, though De Laurentiis - who is demanding that any suitors meet Higuain's €94m release clause - claimed the deal was dead in the water.
