Reckon it will be a lot more than that - simplest solution would have been to restrict ticket sales to Season Ticket holders only (therefore self-policing the distribution), similar to the cup final and before the PATG punters get their hackles up, I'd bet everyone who wanted a ticket and was a genuine 'well supporter would have got one through that method.
Like MelvinBragg earlier, I'm seriously considering whether it is reasonable to take my 10 year-old grandson due to this situation.
