The Serbian centre-back was a fundamental part of now Anfield chief Jurgen Klopp’s BVB side, following him to the club from Mainz before starring in two Bundesliga title successes as well as the fondly remembered run to the 2013 Champions League Final.
However, since the exit of his former boss over the summer, Subotic has been overlooked on a number of occasions by new Dortmund head coach Thomas Tuchel, who has afforded the 27-year-old just 180 minutes of Bundesliga football so far this term.
And now reports claim that the rugged defender could be sold altogether for a knock-down fee next month, which will surely alert Klopp – a move for the player was mooted prior to his official unveiling on Merseyside.
Subotic is one of the German side’s top earners, and with Mats Hummels and Sokratis Papastathopoulos currently Tuchel’s undisputed centre-back pairing, the BuLi giants cannot afford to keep him on the bench long-term.
However, Liverpool may not heave a clear run at the Eastern European, with other teams from across the continent interested.
