Not really. United have earned their revenue in time being one of the top 5 clubs for so long under SAF. This can be done. 15 years ago AM was in segunda I think. Now they are a top 10 club ran with fairness and competence.
The problem with oil clubs, and PSG is worst of them all with Chelsea the "best", is that they want to acquire Barca/Madrid/United/Bayern etc. status record time purely by spending. It's aqcuired status in a long time vs bought status by financial doping in a matter of years. Of course at the base of most success in sports is money in one form of another, but by equalling Qatar with the acquired status of the big clubs over many decades you're brushing over a lot of differences.
I can't believe they're trying to justify it.
The fact they're picking apart teams like Man Utd, Real Madrid and Barcelona.... is incredible. We have rich histories without spending big amounts of money to get there. They're trying to rush there without playing by the rules.
They should be thankful that a billionaire owner has pumped millions/billions in their club, but they're trying to attack other clubs for playing by the rules. There is a reason why a lot of people hate City, Chelsea and PSG. They all have egos, and they think they're doing this all legit. There is a reason why teams like PSG and City want the FFP gone.
If we were owned by a billionaire owner and spent beyond our means in regards to the FFP, you wouldn't see me attacking other clubs.
