I have been hearing this excuse since I don't know when...
As a businessman (not necessarily a billionaire), you grow a club by taking the slow (and difficult) route, as so many midtable clubs have been doing for years. We are talking here about how Pathetico (who I hate, but nevertheless) grew under Simeone and changed status. They way they did it over many years, it's how it is supposed to be done for a club to change tier.
How it's NOT supposed to be done is by breaking all rules and wanting to buy success immediately, what City PSG did, and what Newcastle wanted to do but did not manage because FFP rules were well in place when they started
No, it's very different with American owners of clubs like UTD or Liverpool, as they bought already established huge brand names, with already established huge commercial revenues
