A substantial of money (100m+) has already been spent on the stadium by Moshiri in exchange for additional shares. Probably a lot more has been put in based on advance payments and orders to contractors and suppliers.
We don't need to secure funding for the entire 500m. We can still sell the naming rights, even if we may not get as much money as USM were willing to pay.
The same people that are saying we are screwed now are often the ones who ridiculed people for saying that Usmanov would fund it and that we'd have to go to the markets and take on debt. What has changed for you, lads?
The stadium is seen as a solution to our poor financial footing - not a financial problem. Yes, this is a financial blow, but I still think the stadium will proceed.
