Yes, there is definitely a difference between the Champions League and League 1 because it is a domestic league, even though PSG is very strong in League 1, it does not provide a guarantee of being able to appear strong in the CL because here every club rarely meets and competes, whereas in League 1 every club is guaranteed. Each has its own weaknesses and can always get great results.
The Champions League is a competition that proves to the whole world that a club that can survive until a certain round is proof that the club deserves to be recognized as a strong club because it is able to compete globally, not just in the domestic league, and like PSG today, if it is able to successfully qualify. from the round of 16 it can be acknowledged that the club is one of the strongest clubs even though it could not reach the final round.
PSG is a developing team and they have yet to prove anything big on the European stage. The Champions League is an elite competition that is really difficult to win, so of course it is natural that PSG have to try many times until one day they succeed in winning it. PSG's dominance in Ligue 1 is a must, they spend a lot of money on it by investing in building their squad.
One day PSG will win the Champions League title in the future, that is a sweet result for a team. Manchester City are exactly the same team as PSG were in the past, but they are starting to find ways to win.
