The problem with this is, when you look at the tickets still available, there might be two in a block but one at the front and one at the back. And I can't imagine a fucking humongous amount of people like going to the football by themselves; some will, some do, but a lot go with friends and families. So this is a bit misleading.
They're properly shite seats to be fair. I've sat in upper North before and it wasn't particularly enjoyable, though that might have been because we were dicked on by Chelsea.
