Napoli captain Marek Hamsik is the subject of intense interest from China's Shandong Luneng

Sportitalia says Shandong Luneng have made a €15m bid for the Slovakia international. However, Napoli president Aurelio de Laurentiis is demanding at least double to sell the midfielder.

But De Laurentiis is prepared to soften his stand if Hamsik makes clear he wants to leave.

Hamsik's father, Richard, revealed last month: "There are three Chinese clubs on Marek, the offer for him is €10m.

"Their interest is serious, but the negotiations are not easy. In China there are periods of bargaining, and the next time will be in the winter, Hamsik still has a three-year contract with Napoli, so now it's all in the hands of the agents, and as a percentage I say that 60% he can leave.

"He has already talked to the president about his sale, now it will be up to (agent Juraj) Venglos."
