There was a game in Germany at the weekend where the ref faced a penalty call and booked the lad for diving, before then having another look and overturning it giving the penalty, which they scored. And then the exact same sequence happened again, with the same player! It was the perfect example though of a human error being corrected. It was also handled with much amusement by both ref and player, which was quite warming to see. Can't be arsed to look the clip up obviously, and not strictly relevant but hey ho
