Ideally we'd have around 20k waiting list maybe around 25k before any expansion is done. Naturally not all of the waiting list will take up season tickets.
Scumchester United has a waiting list of around 100k ish. Arsenal is around 45k. Liverscum 25k, Spuds around 80k, couldn't find info on Man City and Chelsea.
However it's fantastic that we have a waiting list. I'd love to see it grow. For direct comparison Everton have a waiting list of 17k. And they've had years to build that. We're definitely heading in the right direction.
