First of all, I never expected that PSG going to drop points against Claremont Foot. I believe when they were playing against each other, Claremont Foot was at the absolute bottom of the table. There is no way PSG should have actually dropped points in the match. And right after that, they have also lost against Newcastle United pretty badly.
I know that the new coach will need some time to actually bring in the results that everyone wants. I also know that the team will probably improve later on. But the improvement will need to happen a little early. Otherwise, PSG will not be able to defend the league title successfully. And that is a big problem. Because this is one title that they have been winning easily and losing this title, will surely mean that the team is not doing well at all.
I don't think this is the first time PSG has lost points against a team that played defensively throughout the match and used counter-attacks to score goals. PSG were held to draws by Toulouse, Lorient, and Clermont, PSG lost to Nice and Newcastle and all of them are defense-focused teams. PSG dominated all those games, but they lost and dropped points due to a draw. This is the impact of Luis Enrique's high ball possession strategy, but perhaps this strategy has not been adaptive enough at PSG so far.
Luis Enrique must improve the defense and midfield, this is a weakness they have had this season. They certainly have reliable attackers, but these attackers will not always be able to make PSG win if their defense and midfielders are not strong and creative enough. A quality midfielder is something PSG is missing, so they must find the right player to fill that position.
