PSG's chances of losing the title in Ligue 1 are very low. Because no team in Ligue 1 spends a lot of money to form a squad like PSG. Every season, PSG forms the strongest and most expansive squad in Ligue 1. And this is why we see PSG's dominance in Ligue 1. Teams like Marseille, Monaco and Lille are not interested in forming a squad by spending too much money.
Also, the current coach of PSG, Luis Enrique, is very experienced. Compared to previous seasons, PSG's squad has fewer star players this season. But even then, PSG has been able to continue its good performance. In the future, Luis Enrique will be able to strengthen the PSG squad even more. Luis Enrique will create a squad suitable for competing for the Champions League title in the future.
Some shocking stuff could happen, not this season obviously because this season is over, but at times some shocking results could happen. Like how Lille once won the league, while PSG had the duo of Mbappe and Neymar as well, or like how in Bundesliga we have seen Leverkusen won last year.
These are all important and do matter because we are talking about smaller teams having a chance. Hell, even bigger example would be Leicester City getting a title for example, that was a huge deal. The problem with these shocking results is that most of the time, the team that manages to get that win ends up losing most of their good players to bigger clubs and they become a terrible team and a terrible result will follow after that.
