We are doing a lot wrong - its not simply a matter of paying bank debt off, its also reclaiming those assets which were sold off and then loaned back to us at a higher rent. Until those things are sorted out we will keep losing money (or at best not make the sort of money that we should be making).
You then have to look at ground expansion (as BBB says this is possible), expanding the corporate side of things (though there is a limit to this, especially where we are and what our fanbase does), increasing our overseas exposure (to further what thebluegibbon says there really is no reason why we shouldnt push hard in the US and Australia), and further strengthening our youth setup, which is - at least until the transfer market implodes under its own insanity - our single best way of making loads of money. I would also like to see an opening-up of the club with regards to its accounts, and ideally an increased shareholding held by fans (the ideal would be every season ticket holder having a portion of the club ) - not so much for sentimental reasons, but mainly because having scrutiny of that kind will inevitably improve the quality of decisionmaking by the board.
