To provide some clarity about what it means for the club to own 75% of itself:
Organization & Management – The professional football club is run under the FC Bayern München AG, effectively an unlisted joint-stock company. The AG is owned 75% by FC Bayern eV, a sports non-profit representing the collective ownership of over 250,000 members [5], and 25% by long-term corporate partners [6].
What happens if investment is needed in the club? E.g. 250m for stadium/infrastructure. Do “fan” owners need to stump up some cash?
that’s where the 25% came in from their corporate partners. Allianz, Adidas, Audi. They’re an A-Class club 
Like @Semmy says, leveraging corporate partners on one hand and simply being smart with their money and paying for it through club revenues + financing on the other.
Of course it’s relevant that Bayern don’t have to compete with a host of other financially flush/doped clubs in their domestic league.
Rumours linking them to Eden Hazard, Dele Alli etc are exactly the kind of level they can pay over the top and get. Not many players at the top of their game now would come to Newcastle even if they are being paid over the top, some might but not many will. But those high profile names that have had bad seasons, not being great for some time now like Hazard would be tempted to get a last payout for a couple of seasons. MInd you, they are still good players to have, but the amount they will have to pay for a start will be tremendously lopsided in terms of value for money.
I read somewhere yesterday that Sarr was one of their first targets, he would be a good start.
Who said anything about state-led nationalisation? No need to just make things up that nobody here is proposing.
And no one’s suggesting supporters are going to throw together a couple of billion and buy the club overnight ffs. Long term means long term. Politically, I’m a socialist - like a lot of Liverpudlians funnily enough - but no one is suggesting a Soviet-style revolutionary takeover in 21st century Britain. Maybe it’s all utopian thinking to you, but a lot of ideas are when they start out. You take things step by step over years, decades etc.
What would you say are the steps from where we are now now to fans buying the club from FSG?
Don’t have my own roadmap for something so long term and there are differing views on this: it would have to be done quite slowly and imaginatively, forming partnerships with different institutions, using the supporters board to promote and consult on the idea, and start to build a case that operating on a mutual basis rather than profit-led is desirable and more sustainable for our club and the game as a whole (as well as more ethical). Eventually, you’d push for a minority stake and go from there.
Relegation still looks likely 
The idea of fan owned clubs in English top flight is bullshit - there is no nicer way to say that.
Thanks for the considered response.
Speak for yourself. 
I sure hope so!
We unfortunately don’t have many spare players that we could fleece them for. Maybe Taki, Origi, Ox and Nat, anyone else doesn’t make a huge difference for them.
400m for those 4? Could even do a ‘buy three get one free’ deal if agree to pay the 300m up front.
I would be reluctant but I would sell them one of our best prospect, Curtis Jones to them for 150mil pounds with a compulsory buy back the following season for 15mil pounds.
Good Ebening
Emery’s probably a good enough choice, given what they have to work with and what they have to do. He might actually save them if they buy a key player or two in January.
