It's got the punters talking and the pundits are in on the act too on Premiership derby day.
Celtic and Rangers' third league meeting was never going to be quiet and so it proved as the home side ran out 3-2 winners thanks to a Kyogo brace and Jota strike cancelling out James Tavernier's double. But one of the key discussion points flared up in the first half when Alfredo Morelos seemed to beat Alistair Johnston in the box and head into Joe Hart's net, but referee Kevin Clancy called it a foul.
Video official Nick Walsh in the VAR room agreed and it's resulted in confusion and rage, with Rangers legend Ally McCoist labelling it an 'embarrassment' on Sky commentary duty. The champions are now 12 points clear at the top of the league and defeat all but ends title ambitions for those in blue. But not everyone is of that scathing opinion on the call that could have put the visitors 1-0 up at a key point in the game. Here are what the pundits said about a defining incident at Celtic Park.
