PSG's loss or draw in the next match will not affect the competition for the Ligue 1 title, which is why this league is less competitive in competition because it is very difficult to break PSG's dominance as the strongest team in the league. The draw that PSG gets will definitely be linked to their performance in the Champions League because the actual competition there is full of challenges for PSG, because the competition in the Champions League will be much more difficult than in Ligue 1.
Winning by two goals when playing at home will make PSG have to be alert when they visit Real Sociedad's headquarters, because if they are careless, it is not impossible that Real Sociedad will turn things around. Even though I myself am more confident that PSG will qualify, Luis Enrique must try to do something so that this match will be easy for them to get a second win.
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.
