I wouldn't want the 4 or 5 to either clear off or go belly up, myself. I like the notion that the field could be levelled, though, to an extent, to make the league more open, rather than them just clearing off or disappearing. That's to me, not what Sport should be about.
I hope, perhaps forlornly, that the UEFA Fair Play thing might tilt the balance back a bit, but I'm not sure they'll enforce it and suspect it might end up being not so much a net to catch the "financial dopers" as just full of holes.
As for wages and that - it's the owners that need to get a grip. No one else can do it.
Fair comment - with regard to the money, some of the owners are so cash rich its all like a game of monopoly to them. It will be interesting to see who will be the first "big club" to go under.
