If we did some form of 'due diligence' e.g. verified their accounts before signing the contract, then I wouldn't be critical of the club. It makes sense that a company trying to break into a new market might use football as a vehicle to do so.
I might start wondering what was going on if they hadn't launched their product five years down the line. However, if they were still paying the invoices then why worry.
I guess that the problem is that they have stopped paying the invoices. Question is how much are we owed?
