I suppose in this modern day our overpaid, well looked after professional footballers can't play unless it is perfect light. I presume in future any game will not be played if there is a hint of fog.
One floodlight went off, 3 perfectly good and very powerful sets still worked. The referee could quite clearly see both assistants from the middle, in fact he could have stood at one end and still see the other goal. There was absolutely no danger to players, officials or spectators, but because Frank didn't want to play we had to stop.
I'm afraid to say Jack Grealish has a brother, Harry Wilson another player who goes down just because an opposing player is too close and unfortunately another ref who isn't prepared to let the game go on.
Overall, poor but that seems to be the norm and average with this group of referees.
