I don't think football is brilliant as it is. Thus my strong opinion on the subject. Seeing the same 4 at the top every year, hundreds of millions spent on players by single teams while other sides go out of business, the widening gap between the big clubs and small clubs. It's not good. It's not a good league system. That should be a fundamental in domestic football. That's the way I see it.
That sounds pretty much exactly the same as how La Liga and Serie A are run. So you can't really go for Barca over United on any of these "principles".
I don't disagree with you for a second by the way. We just need to see that the Prem really isn't uniquely bad at all. It's the norm.
