But let's not forget that these guys have a limit on how they can play with a strong body. They will retire at an early age, and they need all the money they can get to secure their retirement. Imagine not knowing any job and living in luxury, and then suddenly you lose the job that you have? Most people in the entertainment industry will suddenly get poor just after years of retirement.
I think for players that receive less this is true. I googled and saw that Mateo Retegui earned $7,750,549 gross in his professional career and that he makes $3.3 million yearly on Atalanta. That's not a lot because even if he plays for 5 years that's only $ 16 million.
It's different for players like Vinicius Jr that make $20 million every yeark and can retire with luxury a lot easier. At one point you don't need more money so thats why he didn't accept $300 million from the Saudis.
