Well, what a load of bollocks. No organisation, connected to an owner or not, is going to lay bare its commercial sponsorship strategy to an organisation that leaks like a sieve, like the PL. The most they will get is a letter saying the deal is at a fair value to the sponsor and if the PL disapproves it, straight to court to get the whole thing thrown out.
The burden is on the club to show the sponsorship is at fair value? On what planet? The responsibility of any director at any club is to maximise revenues for the benefit of its shareholders. The PL has a problem? They can prove it.
This is just like the way they referee matches. Employ stupid interpretations, then when they are found to be stupid, change them into something more detailed and more stupid. It really is mind-boggling how badly is run the whole organisation.
