For football clubs, debt can be catastrophic, leading to the potential for administration, winding-up orders or points deductions, which can all be applied if a club is run badly enough.
The majority of clubs are in debt but, for most of these, it doesn't matter because they could be in a position to pay it off, if they wanted or needed to.
For others, though, it endangers their future as a club. Teams such as CSKA Moscow make this list, but their revenues aren't close to covering what they owe.
