With the greatest respect we are not Southampton or Coventry. It's no surprising that Southampton struggled seeing the Dell was what 14k capacity?
But even so I'd imagine the stadium is bought and paid for now. Which seeing even for a flat pack stadium like theirs would still cost over 100 million, means they aren't in that bad a place. Had we had the balls to move to King's Dock we would have been laughing. 30 million seemed a lot back then, just as 500 million does today. Who knows what it will seem like in 20 years, but throughout the course of the last 120 years it shows it will be more manageable than it is now.
