As a back-up to this, banks tend to insert 'payback on request' Ts & Cs. Therefore, in theory, a bank loan is just as instantly repayable should it request so. The advantage the club has of using TTA is that (as I have said above) the club doesn't (legally) have any assets and therefore would struggle to gain loans to the extent that it currently has from a financial institution.
Just a guess but it wouldn't surprise me if:
1. The company that owns the land owns the club.
2. Finance from TTA (if borrowed from a bank) is loaned by the company that owns the club and charged against the land.
3. The company that owns the club finances the losses of the football club through an inter-company agreement between companies in the same group.
4. In order for this to be viable the club (and potentially other companies) provide this said parent company with an income so it can continue as a going concern.
Just a thought mind...
