Danny Rohl, meanwhile, tasted defeat in his first Old Firm experience following successive domestic victories this week, but will be proud with the effort of his players after captain James Tavernier’s late penalty in normal time following a handball by Anthony Ralston forced an unlikely extra 30 minutes despite Rangers playing with 10 men following Thelo Aasgaard’s first-half dismissal for a dangerous high tackle on Ralston. Celtic had initially taken the lead through Johnny Kenny’s header after an own goal by Nicolas Raskin was chalked off for a marginal offside call against Daizen Maeda.
