After this season is finished they should change the law to something more common sense but bot before IMO. Just have VAR show the evidence of the ball touching the arm. And use this disallowed goal as the baseline to judge everything else against. I don't want to see Liverpool for example benefiting from a change in the law or it's interpretation because they got it wrong in our case which cost us 2 points. Let them also suffer the same faith and perhaps the same points loss.
