Currently PSG is not a suitable team for talented young players like Lamine Yamal or Osimhen if they want to achieve a brilliant career. PSG are one of the top teams in Europe but they are almost never one of the favorites to win the UCL. They dominate Ligue 1 and almost every year qualify for the UCL. But Ligue 1 is not a league with high intensity and strong teams. A team with a very large cash capacity like PSG can bring in any player they want. But not all players need money, especially if they are young players. I think it would be wiser for young players to choose career over money.
There is still plenty of time for young players to think about money matters if they are not planning to retire early so it would be much more appropriate for those who are still young to think more about their career in a more competitive team even if it is not at PSG. Because if you want to hope for the UCL trophy, of course PSG is not the right choice at this time even though we all don't know what condition PSG will be in next season when they return to the UCL competition. But still, young players should be able to pursue their careers in teams that have the potential to win the UCL, not in teams that always fail to get the UCL.
