What do you mean by PSG not having good quality players this season? Are you saying that Kylan Mbappe was the only quality player PSG had? Most of the key players of PSG like Dembele, Marco Asensio and Lucas Hernandez. These are still good players that are first squad even in their respective national teams. PSG is perfect in their local league just that they are yet to retain good status in European competition Although it is too early to say and I believe they still stand a chance at that because the competition is still very early.
Yes, they are good PSG players at the moment, maybe what he meant was the star players in it like Mbappe, Neymar or Messi while they are currently gone and the last one Mbappe left the team, he is the only star player who has a strong mentality among the others so that PSG's appearance in the UCL is not optimal, they are indeed not in doubt in the local league but in the UCL their chances are getting smaller than usual.
In this season, we are having too many good players into PSG even we are having not big names but still things are at the good level with their performance is also decent in last four games they are having 1 win 2 draws and 1 lost against Arsenal in London which is making some concern, but Luis Enrique is well experienced coach, and he can manage things better in coming matches as they are still undefeated into Ligue 1.
We will have first challenging season for them in French League because things are on level and Monaco and Marseille both are bringing themselves to the level of PSG which is interested with fans will be also had first time good end of the season even still PSG is having good chance of win.
In Champions League, their chances are not good enough for have spot into last four because most chances we will have them into last 8 with their current squad need more time for have better results into this event.
