Neither us or the Mags are money makers for some time. I reckon a conservative estimate is that it'll be 5 years before we make a potential operating profit for an owner spending the money necessary to get near the PL.
We won't make money in the Championship, we might break even with a frugal owner, but that will be similar to our position now in some ways.
There's a reason why people seem to walk away once they start delving deeper. It's not just us as a club, it's any 'sleeping giant' - you've got to be willing to gamble £100m+ before you see even a penny back, let alone make an overall profit on your investment.
I'm sure someone will do it though, some day, but if they do it will likely be ego driven.
