I don't know enough about this sort of thing so I have probably missed a key step here, but it sounds as if...
The bought the club with money released from the equity in the stadium, that line or credit hasn't yet been maxed out so they can continue to fund the club, but the charge for this is 12k per week.
Assuming they have paid less to borrow the money than they are claiming, they could in theory be taking 6k a week profit out of the club.
I'm not sure if they put any cash in or if it's just a smoke and mirrors thing.
