Sounds like UEFA is giving PAO the chance to sell some players in the coming transfer window and then revisit the issue after that.
As for the idea of asking the fans to donate, it's great ... in theory. But given the current situation why should the fans donate. There is still no transparency on what the exact financial situation at the club is. At the very least a sincere administration would offers shares to the fans. But apparently that is the bastion of rich owners only. Fans should just donate and not ask questions apparently. I'm not even a PAO fan and this situation is frustrating.
As an aside, if the fans actually could get organised and get 300,000 people to donate 50 euros each, you don't even need a "rich" president at that point. You have the ability to run it for yourselves. A true fan club.
