Skrtel became frustrated towards the end of last season and had been attracting interest from his former boss Rafael Benitez at Napoli.
The player's agent Karol Csonto has admitted that the Italian club are unlikely to be able to afford to Slovakian international.
"Martin to move away from Liverpool? I specifically say that Skrtel has never said he wants to go away, then it depends on the Liverpool market because everything could change," he told Tuttomercatoweb.
"It's true that the last two seasons were difficult but in football in can happen.
"Napoli? I think they haven't the financial possibilities to take him. Liverpool has not decided a price because they don't intend to sell the player. Anyway, I don't think Napoli can afford his wage."
Skrtel has also been linked with a move to Arsenal this summer.
