But I think PSG is not a weak team when compared to teams from other leagues. PSG dominates Ligue 1 because other teams are weaker than them, but I see PSG can also become one of the best teams in European competition. PSG made it to the semifinals in the UCL and that shows their level. It's just that they have never been among the favorites to win the UCL in my opinion.
From my point of view, PSG is a club that can be said to be mediocre when compared to clubs at the top level of the Champions League. It cannot be said to be weak. PSG is indeed the best club in its own league but is not a strong competitor in the Champions League.
PSG can sometimes perform well in the Champions League but they can't last much longer, at best they only reach the semifinals after which they will face opponents at a level above them and lose. Last season was actually a good opportunity for PSG to return to the final or become runners up because they didn't meet Real Madrid, Bayern Munich or Manchester City at the start, but unfortunately they couldn't face Dortmund, whose performance was unstable at that time.
Next season they will face the Champions League without Mbappe, I don't think they will achieve good results like last season.
