In my opinion, the most important aspects of a new stadium are:
- Greater corporate capacity (essential to larger revenue).
- A better match day experience, eliminating restricted views and therefore enabling more people to go to the match.
What isn't important:
- Penis-measuring.
- A capacity that looks good on paper.
If you looked at it without Blue-tinted spectacles, somewhere in the region of 52k-55k would probably be absolutely ideal. I don't think the general match day revenue is as important as it used to be, considering TV income now dwarfs it, and a good corporate capacity will significantly boost our match day income anyway.
Add in naming rights, non-football events throughout the year, and facilities like bars and restaurants in a more central part of the city, and our new stadium becomes a huge asset. It would be capable of holding Europa League Finals and European Championship matches as well. Would a 60k stadium in a nondescript area of the city have the same non-matchday attraction? No chance.
