A brand new stadium still needs money spent on it to keep it in good nick. The Goldstone never had any serious money spent on improvements/repairs during the last 30 years we were there apart from the Lego Stand and a new roof on the North Stand.
We'll find out in March when the financial accounts are announced. I reckon a lot of debt will get shifted into last years accounts so that the accounts for this season scrape into the FFP guidelines. There are no penalties imposed for a loss in the 12/13 season.
