Napoli president Aurelio De Laurentiis has warned Chinese clubs of his price for Marek Hamsik.
Hamsik has offers from the Far East and admits he'd like to make the move to the Super League.
“I wanted €35m, everyone said €30m and then they offered me €15m," De Laurentiis told reporters after a meeting with Neapolitan mayor Luigi De Magistris.
“Indeed, not even that: a player who has been playing in China, and if you ask me someone who plays in China has forgotten how to play in Italy and in Europe.
“If they don't bring me €30m by Monday, it'll become €40m."
