You've got to be realistic about that, all that money wouldn't have been enough to cover wages and running costs. SISU have run the club into the ground, but they (or rather their investors) are the ones funding the losses, not a couple of hundred pounds each a year from supporters.
Hang on, you can't have it both ways. Either Sisu have run the club (into the ground or not) and are therefore responsible for the costs of the business and the income of the business. Or it's all Mike McGinnity's fault and Sisu have been funding losses that any competent management team would have reduced. If they reduced costs while also reducing income then that's just poor management.
Every new chairman we're told how the club is wasting loads of money and how now they aren't. We had it with McGinnity, then Ranson, then Delieu and now Fisher. Each one claimed to have streamlined the club. FFS McGinnity went as far as trying to rebadge the club to save on printing costs, yet when SISU arrived, it was Ranson telling us how we're wasting loads of money and we'd soon break even after all the cost cutting. Then Delieu came in with apparently a remit to cut costs and got us relegated in the process, but it was all worth it because we now had a club run sensibly. Then Fisher comes in and says the same again. Now we're still apparently overspending and need to "cut our cloth" so much that without a massive expenditure on a new stadium or a new lease we won't earn enough money.
Sounds about as financially literate as your average Tory chancellor.
Much like a Tory chancellor, I suspect this has less to do with a wish to improve the finances of the club and more to do with an ideological point of view.
(this rant not aimed at you, just at an endless stream of chairmen telling us that they need to cut costs with no seeming end in sight)
