Not sure where this idea that Scruffy Jim and Khaldoon are good mates has come from. I've never seen or read anything to suggest this.
There was a Mike Keegan nonsense piece about how Ratcliffe text him a congrats after the Treble that was "warmly received" whatever the fuck that means. But Keegan is a mouthpiece and says a lot of crap.
I'm sure they share some common interests because they're in the same businesses. This is because Khaldoon is in essentially every business sector one way or another, he knows thousands of people.
I'll give you an example. Tony Khan is the "owner" at Fulham. Tony Khan owns a wrestling company called AEW. Khaldoon is the CEO of Mubadala. Mubadala and Silver Lake own Endeavour which owns TKO which owns WWE. So Khaldoon and Tony both own wrestling companies and football clubs. Because Abu Dhabi/UAE own everything.
