Liverpool reportedly have a 60% chance of signing Borussia Dortmund defender Neven Subotic during the January transfer window.
The 26-year-old has been linked with the Merseyside outfit in the last few weeks.
Subotic spent seven years playing under Jurgen Klopp, and there are reports that he could reunite with the German at Anfield.
According to Bild, Subotic is likely to leave the Bundesliga club next month, with Liverpool expected to be a contender for his signature.
The Serbian is believed to be available for around £3.5m.
