We do NOT need a stadium bigger than our current one. Two reasons a) we will inevitably return to the Championship where it’s just not needed, few clubs traditionally much bigger than us fill theirs and our fickle fan base is no different b) the supporting infrastructure isn’t there, nor can I ever see it being built - Christ, have people forgotten how hard it was to get planning permission?!! You need to fund 2 public enquiries to drop a kerb in these parts, never mind the sort of change necessary to support e.g. another 10K spectators.
As said earlier 10k extra supporters now = extra £££'s for the Council.
It'll be galling but the club could now probably get a Vivienne Westwood designed stadium through planning these days.
