Of course, in my opinion, PSG is favourite as well. Because I just can't think of another team which will actually be able to give good competition to PSG for the title throughout the whole season. I think the competition is going to die out towards the end of the season. And PSG will be the only team to still stand tall. Even with all the problems that they had to face in this season. Monaco and Nice did very well to actually be at the top of the table right now. The one team that has actually surprised me is Brest. But recently it seems like the good performance phase is over for them.
It's too early to take such conclusion while we have not yet seen how consistent the middle tier club like monaco and nice. These clubs could become a hard rock to be passed by PSG. We have not yet entered the middle season.
I think that the current standing can also change anytime. you have not yet seen how consistent PSG till the middle of season. There is also probability for mbappe to leave from there as well.
This is my reason to make sure that if everything goes well for PSG till the middle of season. You shall also aware about how nantes or even reims can also perform so well this season.
I remember when nantes was performing so badly last season but the coach has made many improvements to the club.
