The Slovakian defender is in the last year of his contract, and has hinted that he is aware of interest from other clubs.
The Slovakia international is one of several players at Anfield currently in negotiations about extending their stay at the club, with youngster Jordan Ibe recently having agreed terms.
However, Skrtel has so far failed to reach an agreement over a new deal, with just a year left on his current contract. And according to him, he hasn’t signed because the offers so far haven't been good enough.
'It's unacceptable for me,” he said.
“I think that such contracts are offered to players who are much older than me or players who have had some health problems. The contract, which was presented to me, makes me uneasy, so I did not sign it."
With fellow defenders Dejan Lovren and Mahmadou Sahko so far failing to impress at Anfield, and Kolo Toure no more than a back up option, Liverpool would be loath to lose Skrtel, who has become a key player since joining in 2008.
The defender has been one of their more consistent players in an otherwise disappointing season from Brendan Rodgers’ side, and being forced to sell would seriously hamper the manager’s long-term plans.
With just a year left on his contract though, there would be a host of clubs willing to take on the 30-year-old for a cut price deal should he decide to sever ties, with the player himself acknowledging that there is interest in him.
“There has been some speculation about the interest of other clubs for my person, but they are currently being addressed,” he added.
