In June 2006, we'd just finished 5th and were a dodgy lasagna away from finishing in the CL places. It surged during the CL season and I believe has gone down again this season without it.
Can I ask where you're getting your waiting list stats btw?
I don't think it will shoot down, its not like we're going to have 20k turning out in the 2015/2016 season. But if our performances on the pitch become worse in the short term, which there's a chance of considering how much we're going to have to spend on it, we will not fill 60k. And not because our fanbase is brick. I am on the season ticket waiting list (well, I'm not really, I'm a member) but I have absolutely no intention of buying a season ticket again. Either at whl or the new stadium. Yet officially, I am one of the fans apparently queuing up to get a season ticket.
I'd just prefer to have a stadium that allows us to bring in a lot more money, that allows more of our fans watch the mighty Spurs but which isn't empty on a regular basis and which gives us scope to easily and cheaply expand further in the future if we're regularly selling out the stadium.
