Rangers inflicted Celtic's first defeat of the season with a 3-0 victory as Philippe Clement's Old Firm hoodoo ended to pile the pressure on the struggling Rangers manager.
Hurting from dropped points at St Mirren and Motherwell, Clement's side were fired up to beat their rivals for the first time since May 2023 when Brendan Rodgers suffered his first defeat at Ibrox.
They were the better side from the kick-off and Ianis Hagi gave the fans a boost when he fired home the opener with just seven minutes on the clock.
Vaclav Cerny hit the woodwork either side of Kyogo's offside goal as Rangers continued to dominate. Robin Propper scored their second with Danilo coming off the bench to complete a comprehensive win with his first touch.
Celtic were far from the best but remain 11 points clear in the Scottish Premiership title race as Clement looks to have won over the fans again, for now.
