If you read my post, it states matchday revenue PER FAN, meaning that the matchday spend for each ticket sold, not overall matchday revenue.
The cost of living and wages in London is significantly higher than the North West and wages are a lot higher as well, so the average Spurs, Gooneror Chelsea fan etc will be able to afford more than the Average United, City or Everton fan for the match ticket or season ticket.....however, if designed correctly, a large terrace - safe standing- rail seats area can keep prices of match tickets affordable for the current fan from Moston, Salford, Gorton etc, with the "fan park" boosting the "spend per ticket" on beer, pies etc, while the corporate lounges on site, can have a sliding scale from pre-match self service buffet and programme for £100 up to five course banquet for £500 in a private box with complimentary bar and table service
The corporate lounges can then be used during the week for companies to hire for training courses, seminars etc meaning that the ground is in use nearly everyday and not just matchday
