In the just-concluded Club World Cup tournament, Chelsea showed that PSG could be beaten, but the defeat will not have any negative impact on PSG's performance next season, and I believe PSG is still a big threat for clubs in the UEFA Champions League because there are a lot of big clubs that are still trying to strengthen their teams to be at the level of the PSG team.
Majority of big clubs that PSG was a threat to watched that finals amd I believe that they have sent an important lesson from Chelsea on how to render PSG useless on the pitch. The defeat of PSG might not have any negative impact on their performance next season in their domestic league but it will in UCL.
I know that most clubs are still strengthening their squad but that doesn't mean that they wouldn't be able to pick form in no time. Next season will be a big challenge for PSG in the Champions League.
Paris Saint-Germain doesn't face any major challenges this year in the French league. The Champions League is the key. They aim to finish strong in the Champions League group stage this year. Last year, they suffered a few defeats in the group stage before qualifying. This year, their goal is to play flawlessly, reach the final unbeaten, and win the championship. With a fantastic team and a great manager, that's not a far-fetched possibility.
