Jurgen Klopp is in talks with former club Borussia Dortmund over the potential loan signing of ​Serbia defender Neven Subotic, according to ​the Mirror.

The report claims the Liverpool boss hopes to add an experienced centre-half to his squad ahead of Friday's FA Cup tie against Exeter City.

The Reds added Dejan Lovren and Kolo Toure to their list of injured central defenders, alongside Martin Skrtel and Mamadou Sakho.

The situation has gotten so bleak that Klopp was forced to recall Tiago Ilori from his loan spell at Aston Villa, despite the 22-year-old having failed to make a competitive appearance at senior level this season.

“In this moment with no centre-back fit, I would say it is a situation where we have to think about going into the transfer market, eh?" Klopp said after Tuesday's Capital One Cup win against Stoke City.

“Two weeks ago we had three centre-backs, that’s a good situation, at the start of the season we had five, now we have none.”

Klopp has an excellent working relationship with Subotic, whom he signed for Dortmund in 2008 after working with the 27-year-old at previous club Mainz 05.

Despite Subotic having made only four appearances this season, securing his release from the Bundesliga title chasers is so far proving tough, with negotiations between the two clubs said to be stuck.

As a result, the Reds have reportedly enquired over a loan deal for Inter Milan centre-back Andrea Ranocchia, who is also wanted by Norwich City.

Liverpool could also turn to Schalke's Joel Matip, whom Klopp denied having an interest in last week, in a cut-price deal, rather than waiting until the summer to land the 24-year-old German.
