Liverpool defender Martin Skrtel has slammed the Reds' latest contract offer and has put his Anfield future in doubt.

The Slovakian defender, who was one of the shining lights in the Merseyside club's disappointing season, had indicated earlier that he wishes to stay with Liverpool for the foreseeable future despite clubs from the Bundesliga and Serie A showing interest in signing him.

Brendan Rodgers has been keen on retaining the defender at Anfield beyond the summer, and reports suggested that a deal will be agreed following the end of the season after the agent had confirmed that talks were ongoing, but the offer seems to have disappointed the defender.

Liverpool have already agreed new deals with various first team members during the course of the campaign and after, and are keen to tie down the defender, who has been a regular in the Northern Irishman's team.

Skrtel, who is 30-years-old, believes that the contract extension on the table is normally given to players who are old or have suffered health issues, and revealed that the offer made him uneasy.

"It's unacceptable for me. I think that such contracts are offered to players who are much older than me or players who have had some health problems," Skrtel said, as quoted by the Daily Mail.

"The contract, which was presented to me, makes me uneasy, so I did not sign it. There has been some speculation about the interest of other clubs for my person, but they are currently being addressed," the Slovakian international added.

The defender, who is currently with the Slovakian national team for their Euro 2016 qualifier against Macedonia, will take stock of his future and re-consider offers from interested clubs before deciding on whether to extend his deal with Liverpool.
