7 points is the gap created by Paris Saint Germain as the leader of the standings with the club in second place which is currently occupied by Marseille. 7 points is quite a distance because Paris Saint Germain is leading, so in my opinion that distance is quite comfortable for them. With all the inconsistencies that occur in other clubs in Ligue 1, I am not sure there is a club that can catch up. The possibility is still there, but the possibility is very small in my opinion. This also requires great luck, because after all it is very difficult to catch up with a superior club like Paris Saint Germain.
I don't think any other team will compete with PSG for the Ligue 1 title this season. Marseille and Monaco played very well at the beginning of the season. But both of these teams are now far behind. Marseille is 7 points behind PSG and Monaco is 10 points behind. It will not be possible for these teams to close such a big gap. Moreover, Monaco and Marseille's performance is not consistent.
Although PSG has lost points in a few matches, PSG is still undefeated in Ligue 1. Now Luis Enrique's goal is to do well in the Champions League. So maybe PSG may lose points in a few more matches in Ligue 1. However, PSG will not suffer much from this. PSG will win the Ligue 1 title this season as well.
