Everyone associated with Rangers is angry referee Willie Collum didn’t award the club a free-kick in the lead up to Celtic’s goal.Steven Gerrard, the Gers manager raged on the touchline, furious Tom Rogic wasn’t penalised for what he thought was a foul on Ryan Jack. Former Ibrox midfielder Lee McCulloch thought it was a foul and ex-Rangers striker and manager Ally McCoist told talkSPORT exactly what he thought about the decision. Jack, meanwhile, was more annoyed that, as the rest of Celtic Park erupted into celebration at Olivier Ntcham’s winner, he was blanked by Collum.“I said: ‘Willie, I thought that was a foul’, but you get nothing back,” he told the Scottish Sun. “It’s: ‘Go away, get out my face’, whatever. 1 “There’s nothing you can say. If you do try to approach to ask why, it’s a booking and another rash decision that’s going to be made on the pitch.“It’s frustrating for players that you can’t actually approach a referee and ask for an explanation.“I feel like I can’t approach him but that goes for most referees nowadays. You can’t approach them, you can’t speak or they’ll book you.” Ryan Jack thinks he was fouled by Tom Rogic Afterwards, Celtic’s players applauded their support, but the Rangers fans forced to stay behind afterwards, didn’t seem to like captain Scott Brown dancing in delight close to the away end.
