IMO, there are many factors that make it difficult for PSG to compete in the Champions League. We don't need to argue when they compete in Lique 1, they even have a high probability of retaining their title. It could be that mentality is one of the things that makes PSG struggle in the Champions League, yes, as you said. But I see it more than that, there are many factors that make it difficult for PSG to become a strong challenger in the Champions League. Actually, we often discussed it on previous occasions, such as when PSG was handled by previous coaches. Well, the role of the coach, players who are not balanced in several lines, such things also make this team not as strong as elite teams from outside the French League. For example, when handled by the coach before Enrique, PSG tended to rely on the MNM trio. They are sharp in the front line, but their midfielders are not creative. The system and strategy also have an effect, especially teamwork, such things also make it difficult for PSG to compete competitively across competitions. Like this season for example, in Lique 1 they are tough and productive, but not for the Champions League.  under Enrique PSG is actually much better in my opinion, unfortunately it seems Enrique is not satisfied with his current squad. the problem is, they do not have a pure striker to be a goal scoring machine in his team. maybe if Enrique still stays or his contract is extended, maybe next season they will maximize their team squad by bringing in new arrivals who are much more competent to be much more competitive and most importantly can compete in the Champions League.
