I have a feeling it'll be the west stand they open up too since that'll look the best on TV, in which case you'd still be behind a goal.
I think that's likely, but I hope not. I think it would reduce crowd numbers quite a bit for casual fans if that is the only place they can get a ticket.
I can understand only opening one side of the stadium if the crowd looks likely to only be several thousand.. but if it's pushing 15-20 as rumored I really don't like it. It seems to be quite an NZ thing too, I can't recall Aussie games where this happens (unless I'm easily tricked by the TV angles...).
Gold Coast used to do it regularly, for different reasons, to avoid extra expense involved in opening stands. Police, stewards etc
Though to be fair the whole GC United situation was a bit unique, Clive Palmer being the nutter he is picking fights left right & centre - including almost purposedly reducing crowd numbers in protest against Robina stadium ground hire charges.
I'd be surprised if WSW didn't have upper tier areas cordoned off when playing at cavernous ANZ stadium/Homebush.
