The agent of Martin Skrtel cannot guarantee the defender staying with Liverpool.
Skrtel has been linked with Rafa Benitez's Napoli in recent days.
"His sale is not certain, Martin has a three-year contract with the Reds and is happy to be part of a prestigious club like the English. Yet the farewell could happen if they were to get important offers.
"But Liverpool at this time has not received any official proposals," Karol Csonto told TMW.
