According to the Daily Mail, Celtic have opened talks with Dinamo Zagreb over a deal to sign defender Jozo Simunovic this summer.
The Bhoys have already signed one centre back already this summer having landed Dedryck Boyata from Manchester City, but manager Ronny Deila may yet be in the market for another defender yet.
The Daily Mail report that Celtic have opened talks over a move for Jozo Simunovic, with chief executive Peter Lawwell travelling over to Croatia to discuss a deal.
Simunovic, 21, has come up through the ranks with Croatia's biggest club Dinamo Zagreb, and is the latest player on their production line of talent, following in the footsteps of Vedran Corluka, Dejan Lovren, Luka Modric, Alen Halilovic, Mateo Kovacic, Niko Kranjcar and Andrej Kramaric.
Now, with Celtic looking for a defender - even if in-demand Virgil van Dijk stays with the club - Simunovic has emerged as their top target, but despite the talks being held between Lawwell and Dinamo, no agreement has been reached yet.
The report states that a £3.5m fee was discussed during negotiations, but Dinamo want £4m. There isn't much between the two figures, which should give Celtic encouragement that a deal isn't too far away.
Simunovic is highly-rated and has been tipped as a star of the future, so Dinamo will certainly fight to keep him despite Celtic's interest - but the lure of playing at Celtic Park is often too much for players to turn down.
