Thanks for the correction, apparently PIF tried to buy out Liverpool in 2008 as well (not sure what happened to make the deal fall through though).
But it kind of feels like Amanda Stavely is running the show at Newcastle now, I'm not hearing any news about PIF making club decisions which I think is good news - I think they should just be pumping money and keep themselves away from nitty gritty club details as much as possible with the reputation they have.
