FFP is such a joke. Multiple clubs dont even know whether they've breached regulations. Meanwhile, the club operating most egregiously beyond its means, and becoming the most dominant club world football has seen in some time as a result, are just dragging their feet as much as possible and avoiding any scrutiny whatsoever by doing so.
The system is broken. Administratively it's a headache for everyone involved. And perhaps most importantly it doesn't achieve the desired result. It's incredibly tiring.
