It's true that it's too soon to draw conclusions about which teams will be strong candidates to win the Ligue 1 title, there are still 31 games remaining ahead of us. We are also used to seeing underdog teams ranked at the top at the start of the season, soon we'll see how the big teams will get rid of them. Ligue 1 has only played 3 matches so far, and the interesting thing I see is that of the three matches that have been completed, not a single team has finished with a perfect result (9 points).
It is normal to see PSG in this situation now. Because they have been making big changes in the squad. Mbappe was also nearly leaving and he has been integrated into the squad again after some issues between him and the team. They tried a trio without Mbappe first. Despite the dominance it didn't work out as they couldn't score a goal. Whenever Mbappe was in the game he made a direct impact on the game with his goals later on. As I said before he is the mainstay for now.
As long as they have him in the starting eleven their win percentage should be increasing by a high sum. But I don't have big expectations from them anyway as I need to see the adaptation process of the new players first.
That's not normal at all mate, even though PSG were left behind by some of their important players, they still have a lot of talented players in their squad, of course there will be changes, but I mean the changes shouldn't be this significant. We can see all this when PSG played matches against Lorient and also Toulouse in the first and second weeks of Ligue 1, how can PSG only get 1 point at home when facing Lorient? it's ok if their opponent is Lyon, Marseille or AS Monaco.
