It seems that PSG has not fully recovered and fatigue too can be part of their problem because they had Played alot of matches last season before going into the club world cup so the players are truly tired as they has not fully rested so it will take a while before we can see the PSG team that was fantastic last season
This season, Luis Enrique has brought in several new players to support his team's quest for another Champions League trophy.
The PSG manager is planning to use some of the new players for less important matches, allowing the first-team squad to rest and prepare for the Champions League.
This approach is more effective for Enrique in achieving the same success as last season.
