The debt has risen because no members of the board have invested a penny of their own money into the club, beyond the original purchase of their own shares. The debt has also risen because the club panicked and took a very short term approach by taking out a 25 year loan for £30m with exorbitant interest rates, meaning we will have paid back £68m when all is said and done. The training ground is impressive, but unlike Bellefield, we do not own it. We once did, but we sold Finch Farm for £2m. It is now worth £16.5m. We now pay £1.25m a year for the privilege of training there.
In dismissing our ability to attract high revenue streams, using such major clubs in world football in comparison is ludicrous and totally unfair. Using fairer comparisons, our revenue streams are less than the likes of Aston Villa, West Ham and Stoke City. We are an 'unattractive club' (or are we, a top 7 club for most of the past decade?) because of the lack of investment into the club, coupled with bad short-term thinking deals, such as the merchandising deals with Kitbag and hospitality deals with Sodexo, which offer up short term positives in no increased losses, but long term problems in no growth, ever. So as costs go up, revenue streams don't, as the fixed amount as per contract goes to Kitbag and Sodexo.
We become more attractive on the pitch by investment into the club by the aforementioned board. The means, buying players during a January transfer window, and not selling players to finance signings. The stadium issue will only ever be solved when the ownership of the club changes, as the current board have an unwillingness/inability to do anything about it, other than hope Liverpool change their mind over groundsharing (which they won't).
