For anyone who isn't receiving emails, the club have sent one out saying that they are still working through them and you will be able to collect up to kick off on tomorrow but to arrive early in case of queues.
I received my email on Monday and was able to pick the tickets up at 10am on Tuesday (no queue whatsoever at that time).
The first question that I was asked was "have you been contacted to say that your tickets are ready?", so I don't think that you can just rock-up on the off chance.
