Personally. I think the Welnix plan is flawed to the core. The idea of owning a professorial football team in this day and age and having it turn a profit is unrealistic. If you want to own a professional football team you have to be rich enough and realistic enough to understand that successful football team most likely equates to loss making business. The sums of money involved are simply outrageous.
I don't think the A League level of expenditure will ever get anywhere the spend of 1 EPL club but I think to run at cost and win do not go hand in hand. They either have to make money and not care about winning or win and not care about losing cash. Eventually if they do win, the players will want to get paid for the output.
I ask anyone to site me an example where it has worked otherwise. I'm not saying they need to break the bank but even break even is a bit unrealistic. If they could live with say $500k loss a year, that extra $500k would make a difference I think.
Or alternatively, find a massive sponsor (ala Vodafone) that wants to plough money away.
