This will, again, fizzle out because of technicalities, i.e, the information the investigators have is probably correct, but is obtained through "illegal" sources, such as the football leaks. They will walk free again, with everybody knowing full well they've been cheating for over a decade.
There is a reason why City don't want to cooperate, because if thay provide the truthful documentation of what they are asked to provide, it won't be helpful to them to say the least.
If they had nothing to hide, they'd just hand over everything. The fact that they don't, proves they are guilty imo.
