The Itchen Corner closure was one of a number of daft decisions made by the Club since Lowe's return, which combined with a lot of people being skint, has contributed to the massive drop in crowds.
By and large, Saints fans are not mugs, and will not just turn up out of blind loyalty, having seen a season of utter crap last season. We live in an area with a very high cost of living and people have to make decisions about what they're sacrificing at home if they spend £50-plus on a day out at football. We'd never get 30,000 crowds in League 1 like Man. City, as our fans aren't that thick.
Saints won't get the lost fans back quickly. I speak as one who hasn't been this season, and having found plenty of other stuff to occupy my Saturdays, don't envisage returning soon to watch a game with no atmosphere now the Itchen Corner has closed and with little sign of the Northam getting back to anything like the Strachan days.
