The decisive goal came in the 33rd minute when Minsu Kim’s effort was saved by Celtic goalkeeper Viljami Sinisalo, allowing Naderi to pounce on the rebound and finish from close range.
Celtic had initially appeared to take the lead when Auston Trusty’s shot crossed the line, but the goal was ruled out for off‑side, and a subsequent effort from Kieran Tierney drifted just wide of the post.
Rangers’ defence held firm after the break, with goalkeeper Ivor Pandur making a crucial save to preserve the lead, while a potential second goal by Olwethu Makhanya was disallowed after VAR identified a handball in the build‑up.
Manager Martin O’Neill introduced several changes in the second half in an attempt to revive his side, but Rangers remained organised and withstood Celtic’s pressure to see out the win.
The result marks Rangers’ second Old Firm triumph in eight days, extending Celtic’s difficult run of form and leaving the Glasgow club to reflect on a week that has been described as disastrous for the green‑clad side.
