Loan, overdraft, revolving credit facility etc...
Bit of a pyrrhic victory given that only reason they don't (if that's true) is because Gaydamak as guarantor had to pay off Barclays (and so is now entitled to be indemnified by the club).
In any case, they clearly owe a lot to a lot of people and are constantly trying to borrow money to make these payments. The fact that they don't have a bank facility is more indicative that no bank will lend them the money and they're having to look to other, hmm less orthodox, shall we say, sources rather than of their financial health.
