Great victory. how did David Munro achieve Category 1 Referee status?

Let’s get the good stuff out of the way first. Once again Celtic showed great character to get a well-deserved victory against Ross County on Saturday, although it has to be said, we certainly weren’t at our best, football wise, but true to Ange’s mantra, “We never Stopped” and that perseverance and resilience got us three points, and lets us go into the World Cup break nine points clear of our nearest rival.Where do you start with the referee on Saturday, David Munro?
