Have there been any league away games this season where we haven't opened a section for sale? The club should know the demand is there, they must know that people want the choice to sit where they want (if they read social media, they'd realise), it just makes sense to open all together.
Well they may well do block by block, which would only cause people to hold off and refresh until the preferred blocks are free, but the club should know that demand will see this as a sell out - so you'd like to think they'd just open it all at 9am!
To be fair to the approx 3000 with tickets, they need to put the 3000 on sale together. It'll be the day after that any left will be available - this will definitely sell out.
I assume that, if they think half the possible allocation will sell, they would rather give their own fans the leftover half that is nearer the goal, diminishing our ability to suck the ball into the net!
