How have you come to that conclusion? There's an extra row of seats at the back, they've been knocking around since the Arsenal game on the East side, and the bar has been ready to fit on the West Side for the last few weeks, presumably the seats are now in place.
So what's happening to the people in front of the screen?
I presume the club has thought about this? For people in row Y in front of the screen, there's no Z to move into. So what's happening to this bunch and the 4 rows in front of them? Surely they can't move some and not others?
