Just a word of caution on the talk about Newcastle joining the big 6. Ignoring the challenges of attracting top level players to the north east, FFP is going to be a major obstacle. And before anybody says 'what about City', you have to remember they were taken over 3 years before FFP started, there was a lot more leeway in the regulations in the earlier years, a lot of the loopholes have now been tightened and ultimately look how things have still ended for them, facing a 2 year UEFA ban. You then have the fact that there is now FFP in the PL too, not just for sides in Europe.
Also if the Saudi's are serious about this takeover and it is to be a Man City type sportswashing deal then why do they want or need Stavely and the Reuben brothers?
If this takeover is legit this time (and there's been so many false dawns so who knows) and there is genuine money behind the deal then one way or another they'll find away of putting money into the club but it'll be a lot trickier and a lot slower than the Chelsea/PSG/City type scenarios where overnight they were spending 100s of millions.
