PSG wants to focus on the Champions League and try to get the title in this tournament but they are not alone. Teams like Real Madrid also want the same thing but it was also hard for PSG to have any achievement in this tournament. Now PSG's first priority is the Champions League because they know winning the French League 1 is not hard for them considering the money they have spent on this team.
Currently, the only team they have raced with PSG is Marseille because of the good performance we saw from them but even Marseille is not strong enough to make any problem for them yet.
Last season, PSG's main rival for the title was not Marseille but Monaco, and Marseille finished the season in 9th place and lost to PSG more than twenty points. In the current situation, it is too early to judge, Monaco and Marseille have the same number of points, but they already have one draw, and only three rounds have been played. In Ligue 1, almost nothing changes, only PSG can have a stable season, the rest will lose points and this is normal.
