Because they are already on their way to becoming successful, they have a hugely talented young squad, a young manager, They are in London therefore have a huge amount of day trippers to exploit, their fans can "afford" the ticket price rises needed to pay of a stadium, there stadium is far too small already as well.
We have none of that, Infact we need more investment than ever to catch up, how are we gonna be spending the 200+ Million needed to get into the champions league? whilst having Fat sam and the waste of space walsh leading us? all while trying to pay off half a billion of debt.
Arsenal "struggled" competing money wise when they had to pay off their stadium and they where is a far greater position, in a far better area of the country to pay it off. How are we gonna do it?
Like I said, all my arguments would go out of the window, if the club wasn't going to be the one paying it off. but we are. Moshiri isn't.
The spurs stadium has been in development for a decade mate. You don't design a stadium, or any building for that matter for the position you are in now, you build one for where you want to be. We're going to be there for another 100 years. Where do you see Everton in 10 years? 20 years?
What Everton should also have is a view of the larger scale project on the North docks. The transport improvements, if they go as planned will potentially make our stadium among the most accessible in the country, that will go a long way to selling a few more tickets, certainly in the away section, and highly likely for Everton supporters across the country.
IMO, showing ambition isn't building to the best of what we can do now, ambition is building to the best of what we feel we can be. For me, it needs to be ~60k, not as a statement to the rest of the Premier League, but as a statement to me that my ambitions as a 20+ years STH and the ambitions of the club I support are still aligned. Nil Satis Nisi Optimum.
Everybody has their own reason for what they feel will suit us, and we'll find out in due course what the reasons for Everton are.
Just as an aside, I can appreciate Everton trying to include the supporters in the process, but most supporters know jack all about any of the processes involved. I'm not sure the capacity question should ever have been asked in the survey, your just asking for trouble.
