Liverpool’s latest injury blow in defence is likely to force Jurgen Klopp into signing a new centre-half in January.
Martin Skrtel had to be substituted in the 3-0 defeat at Watford and it is expected the Slovakian will miss up to three months with a hamstring injury.
In addition, Dejan Lovren is also out until the new year, Joe Gomez has been ruled out for the season and Thiago Ilori is on loan at Aston Villa.
This leaves Klopp with only Mamadou Sakho and Kolo Toure available as the only senior centre-backs available.
There are doubts over how much the Liverpool boss trusts Toure, with the German opting for Lucas Leiva as an auxiliary central defender once Skrtel had to leave the field at Vicarage Road.
According to the Daily Mirror, Borussia Dortmund’s Neven Subotic is one target – although the Reds may struggle to tempt Klopp’s former club into selling the Bosnia and Herzegovina international.
The same paper suggests that Liverpool have already made an approach for Schalke’s Joel Matip, who is out of contract in the summer and could be available for around £4million in January.
Klopp previously said that the club are unlikely to bring in any players in the upcoming transfer window, although the signing of Red Star Belgrade youngster Marko Grujic is thought to be imminent.
