The handball rule is insane to me, I don’t think the first half one today was a penalty, it certainly wouldn’t be under any sensible rule. However, a ball going into the net has struck an arm, how is that not a penalty but a ball bouncing down off a defenders arm in the box when it’s going nowhere is?
It would be far from perfect but the rule I would put in place now would be, if an arm obviously obstructs a pass, cross or shot at goal from the attacking team then it’s a penalty, regardless of if the arm was in a natural position. That at least seems to be objective rather than the current rule of “whatever the VAR feels like today” that we currently have.
