The German’s options in central defence have been limited by injuries to Joe Gomez, Mamadou Sakho, Martin Skrtel and Dejan Lovren. Kolo Toure also struggled with cramp in Tuesday night’s win at Stoke City.
Maddock claims that Klopp is keen to recruit an experienced player in that position before the Reds travel to Devon for their FA Cup third round tie with Exeter City on Friday.

As well as Subotic, the Reds have been linked with a move for Inter’s Andrea Ronocchia by Tuttomercatoweb.
