That league is completely unsustainable. Am not sure why it would be a target?
I agree that looking to exist within our means is a much better option, even if that means we fluctuate between the Championship and League One and go on good Cup runs.
There are a lot of steps we can take to increase income though. We can grow our fan base further, Club could look at concerts during the summer, I'd expect the academy will start producing good players over the next few years and mix in some good Cup draws with Premier League Clubs and we can be much more sustainable.
