They can't capitalize on their advantage on everything, which is a bad thing in my opinion. Maybe this defeat doesn't affect them because they are still at the top of the standings with a pretty big point advantage. Actually I'm not too interested in fighting for the title in Ligue 1 but I would rather see how they are in the Champions League, but again and again they also fail for the umpteenth time in the Champions League. The Champions League is still too difficult for them to beat until now, they are still at a level that has not been able to achieve that success.
The Champions League is still a difficult competition for PSG because with a sufficiently strong squad depth this season they have not been able to bring big changes to their journey in the Champions League arena. a strong squad and their players are full of experience in the Champions league also doesn't have a good effect if the coach still lacks experience in the champions league so there is no strategy that is too precise when they meet strong teams from other leagues like when they faced bayern munich where psg lost from leg first to second leg.
for next season most likely some players will leave and psg will not be as strong as this season. There are many rumors that Neymar and Messi will leave PSG, will that indicate that PSG next season will again reap difficulties in the Champions League and will fail again. worth the wait.
