I believe that the reason they don't blame Mbappe is because he does his job well on the field and this is something visible to all people when they watch PSG games, when PSG doesn't score any goals yet they see that in that game in which he He didn't score a goal, he helped the team a lot in other ways. and when we look at the available budget that PSG has and what it has done, then there is no way not to blame the management and the coach when there are bad results. For example, this season, this squad that was built, what is its objective? win the European champions league? win league 1? If we ask any PSG fan if they see this current squad as being capable of winning the European Champions League, I believe the answer will be that they don't see this squad being capable of winning the European Champions League.
PSG signed Messi, Neymar, Di Maria and other good players in the past seasons, but they were unable to hire a good coach and keep all the good players until they managed to win the European Champions League. and as a result we are seeing the team's performance drop, this is the fault of the management who don't know what they want. When there are good players on the market the management doesn't go after them, but then they sign players that don't make any sense, there were Lewandowski, Haaland, and other good players that in the past they could spend money and buy and that today would be very useful in the attack of PSG, in midfield and defense. PSG's management has been a disaster in the transfer windows and in hiring coaches
It would be very unfair for anyone to blame Mbappé for the teams misfortunes, cause he's currently the most outstanding player for the club so far and had scored a good number of goals at the early stages of the tournament to keep them were they're currently and if he didn't maybe they've really dropped in the standings, at this point no one has to personally be blamed cause a team that's under rebuilding process sometimes suffer defeats for a while before they pick up again and I believe PSG are currently facing their worst times currently, but they need to be calm and work together as a team to get a better result in their next matches.
PSG might be able to secure their domestic league title but winning the UCL trophy would take a miracle cause a team that can't win against Newcastle is not ready to win against teams like Bayern, City or even Realmadrid that are in a very good form currently.
