The reason for PSG to usually fails in the Champions League is mostly because of their unbalanced team and the players they bought just because the players are famous, I think they need to have a better management team and we know other reasons for them to only win French League is because if not having a good competitor in France to make them ready for the harder matches in the champions league.
Now that's what I said where PSG will find it difficult when they face the strongest team from another league in the Champions League. Therefore Luis Enrique must be able to make a nice change for PSG in the Champions League this season.
If you look at the quality of the PSG players this season, of course they are still strong enough because the players recruited this season are of sufficient quality to make a big contribution to the team in the Champions League.
In Ligue 1, At the start of this season psg also did not make a good start because the two matches that had been played ended without a win. Of course they must be able to win in the upcoming matches to be able to return to maintaining their concentration to get full points in every match.
