Can't see that ever happening, sadly. Despite the poor fan experience the London Stadium generates a lot more money due to its vast capacity and the number of 'tourist' fans who will pay to see any PL game (though many of these would disappear in the Championship). There have been improvements and if they ever have real success the atmosphere would improve.
We got a new carpet around the pitch & a few beer shelves but that's about it as far as improvements are concerned...
To me, there's 3 options:
1) the stadium stays the same - an awful, horrible experience for home & away supporters.
2) the place is knocked down & rebuilt as a proper football stadium (i don't know if that would even be allowed in the first place & we would need to have rich, new owners to fund it).
3) build a proper ground somewhere else (could someone even find suitable land within Newham & again it would need extremely wealthy, new owners).
Regarding extra income re the extra capacity. When we first moved in i believe it held 60k but i distinctly remember David Gold saying that that equated to only an extra £11m per season which was flaming ridiculous, if true. We moved for an extra £11m? Fucking hell...
I'm in no way wanting to come across as 'poor us' but all these are just facts.
Gold, Sullivan & Brady ruined the club & it may well not be fixable.
If ever i pass by where the old stadium was, i just feel sadness & anger now.
