So do you think that is indicating we had steamed i.e sold through 2100 tickets by 10 past 9, if only 900 remain.
I don't think 3000 were on sale from the off. It's difficult to say because I first got access just before 9:10, but given the payment processing issues, it seems likely that not many were sold in the opening 10 minutes.
It could be that only something like 2,500 were put on sale to fans. I would imagine this game is high demand for club friends, partners, staff and family etc.
