First question is do you want Arsenal to spend more than they make (i.e. operate at deficit) within the confines of FFP (hahahaha)?
Then you have to ask if you care about moral/ethical milieu of ownership.
And most importantly, do you want a leadership/ownership group that is involved directly in football matters?
And critically, will they hold the management structure accountable without being totally reactive (ie., manager merry-go-round).
I really think Kroenke vs. Usmanov isn't going to change as much as people think - the club operates the way the club operates and I think we are fooling ourselves if we somehow think Usmanov is going to open up his own wallet and operate the company as a financial losing operation.
The biggest thing for me is that we don't have a massively meddling manager (e.g, early Abramovic) but someone who WILL hold our manager accountable and is willing to make changes when they are needed - right now this is the biggest concern I have about Kroenke - he seems to be erring on the side of caution and stability rather than saying "f*ck this, we are moving forward, risky or not - we need to plan for the next decade plus and the game has changed..."
And to this point, don't see Usmanov fixing this either, as long as AW is around. To me, this ALL starts with AW leaving. The balance of power can then be addressed and proper structure and support and accountability can be restored. We have let that completely get f*d up, following more/less the ManU model, but we didn't have Fergie or his money.
