Callum McGregor and substitute Callum Osmand scored in extra-time as Celtic emerged victors in an epic Premier Sports Cup semi-final against 10-man Rangers at Hampden Park. With former Hoops boss Martin O’Neill back in the dugout as interim manager after taking over from Brendan Rodgers last Monday – along with Shaun Maloney – Celtic took the lead through Johnny Kenny after 25 minutes and then Gers midfielder Thelo Aasgaard was shown a straight red card by referee Nick Walsh for a reckless challenge on Anthony Ralston.
