Yes and no-one is debating that, what we are debating is that fans and players are punished when a team gains an advantage from breaking rules, be it on field or financial.
NF clearly gained an unfair advantage, if we play Arsenal in the final of the EL and Bruno is suspended, and so is Aubameyang, but Bruno plays because of poor paper work, of course we’d lose the final retrospective, regardless of fault because gaining an unfair advantage is the point in question.
As for who’s responsibility it ultimately is to not play a suspended player, it’s the joint responsibility of the
player and the club, not the county FA. So yes, they got a little fecked over by trusting the county FA info rather than their own info, but both the club and the player should know and also have paperwork showing how many yellows the player has accumulated.
