I think the issue is that for offside they draw lines and you can be a mm off (objective). For a penalty they ask “was it a clear and obvious mistake?” (subjective). They need to sort this out. Lost count of the number of times that the comma say “no penalty but if the ref had given it then it wouldn’t have been overturned”. So it was a penalty then? And some **** in black ****ed up but you don’t want to show him up?
