According to The Mirror, Borussia Dortmund have told Liverpool that they won't let Neven Subotic leave on loan - and would only accept a huge offer for the defender.
Liverpool scraped a 2-2 draw against League Two side Exeter City in the FA Cup on Friday, having trailed twice against the Grecians at St. James Park.
The big problem for Jurgen Klopp was his defence, as he had to start Tiago Ilori and Jose Enrique at centre back, with a spate of injuries hindering him right now.
The likes of Dejan Lovren, Mamadou Sakho, Martin Skrtel, Kolo Toure and Joe Gomez - arguably Liverpool's top five centre backs - are all out injured right now, leaving Klopp down to the bare bones in defence.
A January move for a defender may be on the cards for Klopp, but The Mirror state that he won't be reuniting with Borussia Dortmund's Neven Subotic again.
Klopp handed Subotic his first-team debut during their time together with Mainz, and then took the giant Serbian defender with him to Borussia Dortmund back in 2008.
The 6ft 3in centre back went on to make almost 250 appearances for Dortmund under Klopp, forming a superb partnership with Mats Hummels whilst winning two Bundesliga titles, the German Cup and the German Super Cup.
This term, Subotic has made just two appearances under Thomas Tuchel, who is preferring to use Hummels and Sokratis Papastathopoulos in the heart of his defence.
Many had expected Subotic to reunite with Klopp yet again in a bid to solve Liverpool's defensive woes, but that may not be the case after all.
The Mirror report that Dortmund have told Liverpool they will not be letting Subotic leave the club on loan until the end of the season, and would only consider a permanent exit if the Reds make a 'significant offer'.
It now remains to be seen whether Klopp is willing to pay a large fee to land Subotic, but with his defensive crisis seemingly worsening by the game, he may need to make a move sooner rather than later.
