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.
In this new season if any team tries to undermine PSG because they saw that they lost the club world cup trophy to Chelsea and so they thinking they ae now any weak will just be doing themselves bad because PSG ha not shown that they lost any form as a result of that loss, they still have their form and depth intact an will be wanting to defend the champions league so we can still expect to see that same kind of fiercely performance and brilliance from them.
