I've been following the sales quite closely and there were plenty of lower tier blocks in the North Stand with availability this morning but none with more than about 60 or 70 tickets in each and that was before the criteria was relaxed at 10am, whereas the rest of the first tier was sold out. I think that, despite the more expensive prices, the first tier invariably sells out quicker than the the third tier - a bit like a lot of our Wembley matches in that sense. And SS3 always seems to sell the slowest out of the third tier stands, probably because more fans prefer a side view
