For a team like PSG with the huge investment they had in this summer and the players they bought to have better performance than last season, it is a shame for them to be in this situation and I think they should work much harder to have better performance because this time we can't even say they don't have a good coach after having a coach like Enrique working in this team.
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.
