Maybe it's too early to draw conclusions? Bayern is also not in first place in the Bundesliga and even City is not in first place in the Premier League. All three clubs are very close to the top and remain the bookmakers' favorites, so it is too early to talk about serious problems.
By the way, as I said, Mbappe scored two goals yesterday, showing that he is in excellent shape and his decline in performance at the club level is temporary.
Drawing conclusions about Monaco winning the Ligue One crown this current season is too early because one is not in the position to know the teams that would earn major trophies and the ones that would be relegated from competitive tournaments. We might be in the position to enlists these teams but we might never know what's coming because football comes with shocking answers and expectations. The France league is tough, the exact same thing happening in England and Germany, witnessing power changing from the reigning champions, perhaps I've hope for some of these teams would bounce back to good shape and go for their targeted titles.
It's not yet week 10, and the current situation is still very changeable. Usually we will see the schemed position after the league finishes the half season, there we will start to see something that will then be used as a basis in predicting what the end of the season will be like. The situation at the beginning is not easy to predict, because almost all clubs are still looking for their form, and although there are clubs that quickly find their form it is not a guarantee that throughout the season they will stay in the same game, it can improve and what we see more is that clubs tend to decline.
