Local rivals Rangers have shown interest in signing 22-year-old defensive midfielder Niko Sigur from HNK Hajduk Split. However, the Canadian international would prefer a move to Celtic; it is reported that the club retains its interest and is likely to resume negotiations for him. This season in the SuperSport HNL, Sigur has made 16 appearances, scoring one goal and providing one assist for the club he joined in April 2023. His contract runs until May 2028 and his current market value is listed by Transfermarkt as €4.00m. In January 2026, reports claimed Celtic agreed to a £3 million deal for the player, while in December 2025, Hajduk's asking price was reported to be €8 million.
