PSG will not lose the Ligue 1 title. PSG is ahead of the second-placed team in the table by a large margin. PSG is ahead by 13 points. Each team will play 10 more matches. It is not possible for Marseille to reduce the 13-point gap in these 10 matches.
They can lose Ligue 1 title in other seasons but not in this season when they have played well and now managed 13 points more than Marseille. The Ligue 1 season only has 10 more match days and with 13 points more than a latest competitor Marseille, it's very big and enough for a strong team like PSG to secure and take a league title.
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.
