I'm really not concerned about the debt, management etc. For me, the main difference is how the club is ultimately run, the ambitions.
I fear JR definition of success would be driving the club value up, leverage the enormous PR potential etc.
whereas, I believe Qatar wants to be the best, win it all, by all means. Which I think is a necessity to be a successful sports club. Do whatever it takes to get to the top, see City, Barca, Real, PSJ.
Not just about spending money, but how. Spending when you are ahead, not the billions Glazers spend when we were already buried down under.
