Liverpool defender Martin Skrtel's agent has confirmed the centre-back is "90% certain" to leave Anfield in the summer transfer window. The 31-year-old has seen his first team opportunities after Jurgen Klopp replaced Brendan Rodgers last October.

The Slovakian international has struggled with injuries and when he was fit, he has failed to impress the former Borssuia Dortmund manager. Since December, Skrtel has started in only one Premier League match and has dropped down the pecking order at the Merseyside club.

Skrtel is the fourth choice centre-back behind Mamadou Sakho, Dejan Lovren and Kolo Toure under Klopp. The Reds have already agreed a deal to sign Joel Matip, who will move to England in the summer and his arrival will see the former Zenit St Petersburg man struggle for playing time.

According to the Daily Mail, Turkish champions Besiktas have expressed their interest in signing Skrtel, whose contract at Anfield will run down in 2018. The player's representative Karol Csonto confirmed Besiktas are keen on securing his signature.

"Besiktas is one of those interested in Martin but we're haven't reached a point where I can confirm Martin is going there, or anywhere else," Csonto told TV Markiza.

"But I can say that it is 90% sure Martin will leave Liverpool, but it is far from closed."

The comments made by Skrtel's agent suggest the Slovakian is set for an exit. In addition to this, Toure's contract at Anfield will expire in June and is a free agent in the summer.

Meanwhile, Sakho could face a lengthy ban for his failed drugs test and should that happen, it will leave the German manager with Lovren and new arrival Matip as the only two first choice central defenders in the squad. Klopp needs to strengthen his centre-back position for the 2016/17 season and the lack of defenders could force him to enter the transfer market to sign a centre-back in the summer.
