It would be all about how the stadium was managed and run and with a good team that actually knows about PR/Marketing ! Also like some stadiums the upper tier could be covered and not used depending on demand
The stadium would also provide other money streams to the club in regard to say music concerts, used for other sports like rugby or Cricket? A good marketing team would try to attract for example England International out of London or try to get NFL game/WWE wrestling due to growing popularity?
A reasonable priced season ticket fee would hopefully say get 50,000 season ticket holders so with say 5000 commercial seats ( rough guess) and depending on away support as we should give a basic number that could be added or decreased depending on relationship with said clubs 10,000 so yjere alone is 65,000 seats/
If club set up one stand as the "family' syand where a family of 2 adults and 3 kids under age of 14 go free? the kids fill the seats and kids will demand sweets, soft drinks, burgers from parents so with good food supplier its increased revenue
Same way with Everton in the Community we could donate tickets to charities and am sure media pr of us bringing for example elderly folks from retirement homes, ex service men/women, schools etc would also add to the charm of "The People's Club" who are there for the People
New stadiums attract walk in guests so thats where the team would target tourists to city, supporters clubs worldwide with fixed reasonable priced tickets
50000 or 55000 stadium capacity is safe bet but Everton needs to stop the "poor little us punching above our weight" attitude Kenwright instilled in club :-(
Imagine us with a stadium that has 15000 or 20000 more capacity then Redshite what sign it paints in city? Who cares if its not full every week to capacity but a new stadium of 55000 or 60000 will increase revenue compared to Goodison and then imagine for a derby to wind them up we only give them 1000 seats and then put a 10000 safe zone between them and rest of stadium? The media fallout would be hillarious ;-)
Everyone will go on about funding now etc that we're struggling for 50000 stadium so why dream of 80000? ulk buying usually ends up cheaper in long run
I hope every year we'll win title even though no one rates our chances and as Everton we need to become the in your face look at what we are doing club
And a stadium bigger than our city rivals is the minimum to expect if we're going to be noticed
