Dirk Gently If the club have any commercial sense, as I'm very sure they do have, I think they will have realised that prices are now getting to a tipping point for many supporters.
At a time when many other clubs are freezing or even reducing tickets, I don't think they will be justified in going for any increases - not only because of the massive negative publicity they'll get, but also because they recognise that next year will be a difficult one for supporters because of the disruption from the building works.
Above all, though, the key fact is that that they need to keep demand high, because within 2 years they'll have another 14000 seats to fill each match. So they know that it would be extremely counter-productive to price anyone else out now, because within 2 seasons they'll need those people back to fill the new capacity. And it's much easier to keep them now rather than try to win them back in 12 months and onwards.
Dirk Gently for Commercial Director!
I fear the present incumbent may not have the same wisdom or foresight!
