can't really see a problem with ffp due to stadium sponsorship, why should it concern the footballing gods, how it paid for as long as it is legal. Do you think they would like a club to go into even deeper debt, because the club want to move their fans into a state of the art stadium, rather than an out of date one.
besides let them try, I'm sure Moshiri/ Usmanov have pretty reliable and expensive legal teams and after the abomination of 12 selfish clubs trying to actually destroy football as we know it, for their own selfish greed. Let them try.
