PSG's mentality in the Champions League always changes every season. This season PSG has good players with great talent, but their performances are still not very impressive. Of course it is still possible to hope that PSG can improve its performance this season with the depth of its squad, but in my opinion everything is very difficult.
So far I don't think PSG is one of the teams that can win the title in the near future, but that doesn't mean they can't achieve it. PSG still has to try hard and make good use of the market to bring in players who are truly quality and fit their needs, meaning not expensive players but whose game is just enough. They need an experienced squad, especially in central midfield and that must be prioritized.
They don't have players that are special players, it'll take some time and seasons before Luis Enrique can assemble that kind of a squad to compete for the Champions League. I do wish at times if he was the coach around when they had players like Lionel Messi, Neymar Junior and also Kylian Mbappe. I know what he would achieve with these lads. They can successfully win the League 1 Championship bit not the Champions League.
They're not ready to win the Champions League, they don't look really good and ready. With Kylian Mbappe also willing to go at the end of the season, that's another weak link you feel? They'll be knocked out of the Champions League in the next round because they'll definitely meet a stronger side!
After seeing PSG performance in the group phase, of course we can judge that they will not be able to go further in the Champions League this season because the other teams are stronger than them. Also with the players, of course they don't have the mental strength to be able to win the championship. Not to think that PSG is weak this season, but they are still not strong enough to be able to overthrow Bayern Munich, Manchester City or Real Madrid this season. I think Real Madrid and Bayern Munich are too strong this season so if PSG faces them of course PSG will have difficulty beating them.
Of course PSG relies on Mbappe as the heart of their game this season because without Mbappe PSG will have difficulty winning. If something happens to Mbappe, such as an injury, it will certainly hinder PSG progress in the Champions League. Because we have seen in the previous Champions League when PSG was still strengthened by Messi and Neymar but PSG also couldn't win the UCL trophy. So it's like there is a curse for them in the Champions League and I hope Luis Enrique can overcome it this season.
