Napoli president Aurelio de Laurentiis has challenged Chelsea to put their money where their mouth is over Marek Hamsik.
The Slovakia international has been linked with an £18 million move to Chelsea in January, if the Londoners can get their FIFA transfer ban frozen.
Asked about Chelsea's interest, De Laurentiis said this morning: "Hamsik will remain here, unless Chelsea make me an extraordinary offer.
"But I don't believe this will happen."
