Liverpool are prepared to block any move for Martin Skrtel from his former club Zenit, according to ESPN.
Speculation has grown recently over the future of Liverpool's Slovakian defender, who was linked with a move away in the summer.
The 28-year-old lost his place to Jamie Carragher last season and has only recently managed to nail down a starting place under manager Brendan Rodgers.
Reports suggest that Zenit are preparing a £16million bid in January for the defender, which is nearly £10million more than they sold him for back in 2008.
Skrtel hinted he was ready to reevaluate his future at Liverpool after his lack of first-team football back in May.
With Rodgers signing four defenders over the summer, including central defenders Kolo Toure, Mamadou Sakho and Tiago llori, Skrtel's chances at Anfield may be limited.
Rodgers, who has recently switched formation to a back three, does not want to lose another defending option as Sebastian Coates is out with a long-term knee injury.
