Wasn't the whole argument of the "ACFC Knitting Circle" based on the idea that people like WelNix should be pouring money into making a local semi-pro league sustainable rather than putting a team in an "Aussie league"? Here - as in the debate of whether the Nix should have "bigger-spending owners" - the belief that there are such deep-pocketed football-tragic millionaires out there and we just need to invite them seems like a curious urban legend.
I of course hold the opposite belief - that there should be a much lower cap on player payments which should help an amateur national league become more sustainable.
I should also add that the top-level (NPL) state leagues in Australia also include the reserve teams of A-League sides.
