You know what. You maybe proved right. You also may not. I personally disagree with you, as I feel there's no way they can not give the pen, as there will be uproar all round if they were to go against a plainly wrong decision after reviewing it.
What I struggle to get my head around, is after years of the current disgraceful system, last night being the latest in a long line of bent corrupt referees, is why people won't give VAR a chance, before they dismiss it. It will never be perfect, but it has a chance to level the field significantly. Can't understand why any blue doesn't want to give it a chance to see if it improves things over the current debacle!!
