It's a good question.
Haven't we covered this when the accounts were released? We're spending too much. Revenues slightly decreased 4% to £84m, but our expenses increased to £108m. That loss was offset by the income you listed above.
I'm not an expert, but I think the business side is 'improving' - we can all quibble about how much - but the footballing department is not spending money efficiently. £5m on Dessers is awful business, for example, but even our wage bill is too much. I think someone mentioned that we have a higher wage bill than PSV (iirc?) despite having comparable revenues? They were streets ahead of us. It's not that we don't 'have' the money, per se, it's that we're not spending it well enough.
I'm hopeful Koppen and Clement will improve things going forward.
