It's always a day packed with talking points when Rangers and Celtic go head to head - but there is one clear issue dominating the post-match debate.
Celtic could have had the opportunity to fire the ball beyond Allan McGregor while trailing 2-1 had Connor Goldson been penalised for a handball in the box, as the ball appeared to strike the arm of the Rangers star following a drive towards goal from Carl Starfelt. Referee John Beaton failed to point to the penalty spot and following a VAR review Willie Collum review the flashpoint using multiple angles but opted to not send the man in the middle to the monitor.
While debate has rumbled on following the full-time whistle, with the talk raging over whether Goldson's arm was in an unnatural position or if the Englishman has made himself unnaturally bigger to block the Swede's effort on goal. The defender's hands were near his face as he got in the way of the effort.
