You are making an unfair comparison...
- Saints were at the Dell whilst in the Premiership playing some of the best teams in the world.
- Brighton at the Withdean in the 3rd tier playing against 3rd tier teams.
- You really can't compare the Dell with the Withdean. The Dell was out of date, but the Withdean is something else! It would put off a lot of fans.
- They have sold 14,000 season tickets because spec wise, the Amex is one of the best stadiums in the country. New stadiums = rise in interest.
Poor views of the pitch like this do not attract large numbers of fans no matter how well you are playing...
What makes you think they have no cash? They have an extremely rich owner that just funded a £95m stadium and is funding a new training ground.
