Indeed, PSG is still leading their competitors in Ligue 1. But they also should not feel too comfortable, seeing the draws in PSG's last 2 matches. If they do not focus on Ligue 1, they could be threatened by their competitors. The league is still long and they must maintain a stable performance.
PSG's next match will face Lyon and Monaco. If they can beat both of them, their position at the top will also be safer. Lyon and Monaco are not weak teams, they are better than Auxerre and Nantes who held them to a draw. So PSG must seriously prepare their team.
PSG must be able to return to winning ways and must not lose even once in the next few matches, because considering the difference in points between PSG and Masrseille is only 2 points, then when PSG loses, there is a possibility that its position at the top of the standings will be shifted.
And facing a team at the top is indeed quite difficult, but on the other hand this also creates a momentum for PSG to widen the points gap with the teams below it. but with the note that PSG must be able to win the match against Lyon and Monaco in the upcoming match.
Marseille and Lille match ended in a 1-1. That made only 1 additional point obtained by Marseille. That makes them now have a difference of 4 points. And if PSG wins against Lyon, it will be an advantage for PSG who can continue to lead the standings.
In another match, Monaco will face Reims, I hope Monaco does not get the same result as Marseille and they can move up to 2nd place in the standings. Monaco will play as a guest, but I am sure they will dominate the match to win.
