While 108,000 does seem a bit ambitious at this stage (!), I think discussions about the Kop and the WBR, and indeed future proofing aren't stupid at all. The Kop is our unique selling point, well one of them. The main stand is fantastic and I'm sure the ARE will be too when it gets done.
The question is of course about money. Now I don't know what it'd cost to build a Kop like that, but I am interested in what it would cost to re-route the WBR like that and in doing so future proofing possible future expansion. Are we talking 10m? 20m? 30m? Is it really that mad to keep our options open?
P.S. Dunno what's going on with thouse huge ball globe things though...
