There appears to be inconsistency in the way that the Advantage Law is being applied. We know it is at the sole discretion of the referee but the length of time it goes on seems erratic. Someone last night said that there had been a protocol to say that the length of advantage depended if it was a Penalty Advantage or a Free Kick Advantage. The implication of his statement was that a Penalty Advantage would continue regardless of ground gained until either side committed another offence (or in his mind until the none offending team scored)and if that meant bringing the PK back 20-30-50 metres that was OK. Sounds nonsense to me but is there any guidance on the application of the Advantage Law?
