"To allow the goal to stand means that advantage was given to the perpetrator of the handball, a new concept"
I take it by 'perpetrator' you are referring to TTA Microscopist. Isn't this predicated on TTA's being a handball offence (and Silva's not?). I think that's what is open to opinion, but makes for good debate, however frustrating it can be for managers, players and fans. I do take the point that if Silva's was considered handball, then it should have been a free kick to Liverpool but evidently wasn't a factor in the VAR decision.
Hi Ref Fan, if the incident had happened in the centre circle then Bernado's "handball" would not, I think, have been deemed deliberate and therefore only TAA's handball would have been penalised. The only reason for considering Bernado's handball is because when TTA handled a penalty would have created a clear goal scoring opportunity - and as pointed out earlier it would have been even more ludricous to allow the penalty to be taken (and assuming it was scored!) disallowing the goal as it was created following the "so called no fault" handball by Bernado. The problem goes back to IFAB who didn't have the wit to produce a proper change to the law that covered this eventuality. Looking at whether the handball "created" an advantage would be a better concept, in my view. Having decided whether it created an advantage then looking at whether it was deliberate or not would govern the issue of yellow or red cards.
Even if Bernado's handball had been seen as deliberate then surely the advantage stops when TAA handles the ball?
