On Wednesday, it was reported that Celtic were interested in another defender, and now, new details have emerged.

The Slovakian centre-back, who has been on Celtic’s radar this summer, signed a new long-term deal with the Sardinian club back in January, tying him to the Italian side until 2029. That fresh contract has significantly strengthened Cagliari’s hand in negotiations, and they are under no pressure to sell unless their full asking price is met.

Obert, 22, is well-regarded within the Cagliari setup, and while the Hoops are believed to still hold interest, there’s no indication at this stage that they’re prepared to significantly raise their offer.

The defender’s name emerged as a potential addition to a central defensive unit that has already seen major changes this summer, with Jahmai Simpson-Pusey arriving on loan from Manchester City and Gustaf Lagerbielke and Maik Nawrocki heading for the exit.

With Obert under a lengthy deal, Cagliari are taking their time in identifying possible replacements before sanctioning any move. It remains to be seen whether Celtic will revisit the deal later in the window, or move on to other targets as they look to balance defensive depth with other more urgent needs in the squad.
