I think one of 2 things will happen...
1: Moshiri puts us up for sale when the stadium is built. However, he will need the team to be in a far stronger position both on/off the pitch to attract buyers.
2: In a couple of years USM return and go full Galactico levels of sponsorship/investment etc
I dont see another outcome.
I dont see a change of ownership myself mate. Ill put it this way, Abromocivh bought Chelsea for 60 mill, hes selling it for 3 billion, hes put about 1.5 billion into it - thats just servicing the asset.
Clubs are investments for these lads, somewhere to wash your money and an investment appreciates in value over time, even with what been put into Everton in Moshiris time will just be seen as a servicing cost - though hes made a bags of it.
