It is difficult to assess this match as the teams played in lineups that were far from optimal. Judging by the statistics, the result is fair, since PSG dominated only in possession of the ball. It seems to me that this result is quite satisfactory for PSG, since nothing threatens their position in the first place, and although this is a loss of points, it is not a defeat.
You can dominate a single match as much as you like, but if it doesn't end with a goal scored, then it's all just statistical games 
Despite its place this season, Lyon has shown itself to be quite a worthy opponent. Lyon's tactics consisted of striking counterattacks and it turned out perfectly in one moment. Another question is that it still did not allow us to win the match with such an opponent as Paris Saint-Germain. However, considering what a gap Paris Saint Germain already has from rivals, this is just a separate reason for dissatisfaction with the result, but not a reason for unrestrained grief and making far-reaching conclusions. 
Nantes have been much better in the second half as they got so many goal chances. Monaco seem to have the most ball possession but they are still having a problem on finding the target. There are less than ten minutes left to the end and this situation is very risky for Monaco. But I think that the game will end by this score.
