Agent Zoran Krneta has told The Scottish Sun that his client Aleksandar Pantic 'would definitely consider' a move to join Celtic.
The Bhoys lost last season's starting centre back partnership over the summer, as Jason Denayer returned to Manchester City at the end of his season-long loan spell, before Virgil van Dijk was sold to Southampton on transfer deadline day in September.
In came Dedryck Boyata, Tyler Blackett and Jozo Simunovic, and whilst the latter has shown flashes of what he can do, Celtic have struggled defensively through the campaign.
Fans have called for manager Ronny Deila to strengthen his backline during this month's transfer window, and recent reports suggest he has a target in mind.
The Daily Mail report that Celtic boss Deila was in Spain over the weekend, and watched Eibar defender Aleksandar Pantic help his side clinch a 4-0 win over Real Betis.
Now, Pantic's agent Zoran Krneta has told The Scottish Sun that his client would consider a move to Celtic Park - and he wants to help Celtic clinch another deal after aiding them in the move to sign Simunovic over the summer.
"Aleksandar would definitely consider Celtic," said Krneta. "They are a big club. I helped them bring Jozo Simunovic to Scotland last summer. I have a good relationship with Celtic and if they want to talk about Aleksandar, we will do that.
“I believe Celtic have had a look at a few players in Spain and Aleksandar was one of them. But there are several clubs interested in him. He is playing very well at Eibar and Villarreal are also happy with him," he added.
Pantic, 23, is a former Serbian Under-21 international currently on loan a Eibar from Villarreal, but his contract expires at the end of the season, meaning Celtic can pursue a pre-contract agreement this month, where he would be able to join for free in the summer.
Due to their previous dealings with Krneta, Celtic may feel confident that they can land Pantic - and give their defence the boost it so desperately needs.
