PSG is slowly starting to recovered and making significant progress, even though they experienced defeat in the match with Nice, it doesn't seems to be a pressure for PSG to continue to improve its performance.
PSG has proven this by beating Dortmund and Marseille in League 1. I thinks PSG would be nothing if not for Mbappe's because in several matches PSG always relied on Mbappe's to be a goals scoring machine for them but unfortunately Mbappe's was injured in this match and was replaced by Goncalo Ramos's even though Mbappe's was not in the match at all. did not weaken PSG defense but instead increased their strength so they were able to score 4 goals without reply, a victory which was quite surprising for PSG fans.
The competition in League 1 look increasingly interesting as the fight for the title between Nice, Brest and PSG, all three of which are in goods condition, but we don't know which of the three club will survive until the end of the seasons and become champions in League 1.
Mbappe does have a big influence on the squad but I don't think he can do it alone without the help of other players as support. If you look at when Mbappe was pulled out due to injury in that match, the attacks launched by PSG never decreased, in fact I saw them pressing even more, so that even though Mbappe was not there PSG could still press. After experiencing defeat against Nice, PSG is increasingly confident even though they are currently still in third place in the standings.
In the next match, PSG will face Clermont Foot as the bottom bottom team so it will be easy for PSG to get full points in this match. Competition in Ligue 1 will be even more interesting because it will give rise to increasingly tight competition for the three clubs in the top three and PSG also have to improve the game in every match so they can return to first place in the standings.
