PSG could have closed the season with even 5 trophies but they failed in the FIFA Club World Cup. In the end this tournament was kind of a part of the previous season. Who could have thought Chelsea would be the one to stop them?

I see some weakness in them against Premier League teams. Eliminating Liverpool and Aston Villa both were also not an easy work for them in the Champions League you know. I wonder whether Luis Enrique will find a solution for those teams too next season...
This defeat against Chelsea has nothing to do with their squad in my opinion, I did t see any changes with the same squad that defeated Real Madrid in the semifinal of the club World Cup, so it is just how football works; they are unlucky and lost to Chelsea in the final.
PSG players and the coach never expected a defeat from Chelsea, they thought they can do it just as they were doing it since the beginning of the competition but they don’t know that Chelsea prepared well for the final and defended themselves well in the final and Cole Palmar and his teammates did well to give Chelsea their second trophy of the season.
This same squad will give PSG another League1 title without any doubt and they can go far in the Champions League next season even though they can still win it, but with the way almost all big teams are preparing against next season, there is no favorite to win the Champions League next season, any team can win the competition.
