I think the PSG team's motivation when playing in the Champions League will be different so it has nothing to do with whatever results they get in Ligeu one.
And it must be admitted that PSG's performance this season has decreased slightly compared to last season, but being able to defend the title in League 1 is not a difficult thing because the quality difference is quite significant between PSG and other teams and financially PSG is also far superior, so it is natural only if there is no team capable of matching them in league 1.
In Ligue1 PSG can still do a lot to get good results with more satisfying results because remembering that other teams are not better than PSG itself. However, in the Champions League, PSG still cannot do much to get satisfactory results because the quality of the teams they face in the Champions League is always different from the teams that PSG often faces in Ligue1. I even still doubt PSG when they visit Real Sociedad in the second leg of the Champions League even though PSG already has two goals in aggregate for the second leg.
To qualify for the last 16 of the Champions League I don't think it's difficult for PSG, they are already ahead by 2 goals in the first leg and even though the second leg is being played at home to Real Sociedad, I think PSG still has quite a big chance because in terms of quality PSG is much stronger. compared to Real Sociedad this season.
In Ligue 1, no one doubts PSG, even before the competition started, PSG was already the favorite to become champion, but the lack of competitiveness in this competition was detrimental for PSG, which could not develop to be able to compete fiercely in the Champion League.
As we saw in the previous season, even though PSG had many top players, they were unable to win the Champions League title.
