If we had started selling to STH, previous bookers and the general public with no history at the same time, this would have sold out on day 1. It only seems a slow 'sell out' because of the staggering of buyers.
As of about 10 mins ago it was 833 to go. So, with the remainder of the 'previous booker' sales today and 2 extra ticket sales for Season Ticket Holders tomorrow - this will definitely sell out - there won't be any general onsale for Arsenal fans to nab them.
