Football was ruined before? Says who? Because clubs spent money like crazy when there were little rules to govern the sport? Yes, advantages were certainly created by those clubs that were able to locate funds to spend and people deemed it unfair, that's why rules and regulations were created to prevent this from happening again and level the playing field.
One critical and striking difference between the likes of Real Madrid of the past and PSG/City of nowadays: Real Madrid didn't have unlimited amount of money like PSG/City does today, if they didn't have the money to spend, they had to borrow it, they had debt and they still do. The same applied to us. You might accuse us of receiving aid from the Spanish government and tax benefit as we are not sport companies (SAD) and you might think this is unfair, but other than that we had to find the money to finance what we spent. PSG and City are not like that at all. If they are allowed to do so, they can tap into their respective sovereign funds and state funds that own them and they have literally unlimited amount of money to spend, without worrying about going into debt and repaying it.
Let me ask you this question: What is the perfect/ideal world for you, newcomer? You want everyone to be able to spend whatever he/she wants on anything and there should be no limits whatsoever? In that case, today it is PSG/City, tomorrow it is ABC/XYZ, sky is the limit, the newer ones, the wealthier ones will push the older, the less wealthier ones aside and there won't be football or any sport to speak of. Is that what you want?
You keep whining about the FFP and how PSG is victimized by it. Exactly how? PSG is facing little challenges in the French league (this season is an exception perhaps), going strong in the CL, what else do you want? Do you want PSG to be allowed to spend unlimited amount of money to buy more players and tie down Mbappe or something?
