Ligue 1 matches are not important for PSG. PSG is sure to win the Ligue 1 title. PSG is ahead of Marseille in the second place in the points table by a huge margin of 19 points. Marseille's performance is now erratic. It is impossible for Marseille to reduce this gap to 19 points from 7 matches. So if PSG loses all the next matches, PSG will be the champions of Ligue 1.

PSG conceded a goal in the 9th minute against Saint Etienne, who is in the relegation zone. The team is still 1-0 behind in the match after 25 minutes. Luis Enrique is playing with his second-string squad today. Dembele, Hakimi, Marquinhos, Donnarumma and Lee Kang are not in the starting XI. Luis Enrique has rested the players. PSG will probably be happy with a draw. So far, PSG's overall gameplay has been quite slow.
You were speaking as PSG would have accepted a draw. With what you consider to be a "second-string squad", they just blasted Saint-Étienne 6-1. That is second-gear, second-string. Guess what, Gonçalo Ramos grabbed two, Lee Kang-in came off the bench and tallied up a goal and an assist? They accomplished it without really exerting their entire might
If PSG was crawling and Marseille had a motorbike, he couldn catch them. Mathematically, it's over. Even the calculators in Paris stopped working weeks ago. The Champions League and the Coupe de France final is the actual show, so Luis Enrique is not just resting players for fun
