So PSG right..

Sorry I'm not too clued up on whats going on PSG except they're rich as hell and they seem to have spent even more than us in recent times. But it also appears that theyre going to continue spending left right and centre. All due to some 'Investment' which by all accounts is legit.
So whats the deal how come they can do this and whats the difference with us?
Or did Platini say its ok for French clubs?
