Wow, you manage to contradict yourself about 100 times in 1 post.
You say it's easy to get around FFP but you acknowledge that PSG & City were sanctioned by UEFA. You say that every club knew on day 1 how to get around FFP but again, you acknowledge that PSG & City were sanctioned by UEFA.
Can club owners use their own or related companies to sponsor themselves? Yes but as we've seen UEFA will bring the value down to a fair market value*. City & PSG tried to get around FFP initially but failed - they were sanctioned and we saw that their spending the following season was directly effected.
We still don't know whether PSG have figured out a way to get around FFP but there are theories that they've managed to sign Neymar by Qatar sponsoring him directly rather than sponsoring PSG and they in turn paying for him. Who knows, if or how they've got around it - what's clear is that any way of getting around it only applies to the state owned clubs like PSG & City, your average billionaire will find it too expensive to do.
*PSG's deal wasn't simply a shirt sponsor so you can't compare it to the value of another clubs shirt agreement.
They are allowed to spend the money in the account, if the owner wanted it, it wouldn't be in the account......Wenger is 100% allowed to spend the bulk of that money....
And you know this how? Why was it being reported that without selling Sanchez, even after banking £35m for Ox, that Arsenal didn't have any money to spend?
I have absolutely no idea if Wenger can or can't spend that money but as I've said, there are people in finance that have speculated that the terms Kroenke's personal borrowings are or will be directly linked to the state of Arsenal's balance sheet. This certainly wouldn't be uncommon, as I've shown the Glazers had (may still do too) a very similar agreement in place with their borrowings and Utd's finances. Again though, I don't know this for certain (I suspect neither do you), it's just a theory as to why Arsenal have kept their cash levels incredible high over the last few years.
