We all have seen PSG this season who managed to win their first trophy, even I'm tired of seeing their x channel which almost every minute keeps posting it. LoL
But with PSG's victory this will be a big motivation for them to perform better, just as a note the UCL competition is not easy even though now PSG is a strong candidate but to win the title in a row is clearly not something you can imagine simply.
They are still expressing the joy of achieving a new history. Let them enjoy it in their own way, however, they are looking forward to it with a lot of effort and money.
Every team that will compete in the Champions League will definitely update their performance for next season. The new season will definitely come with new competition. PSG will definitely still realize that they have not dominated in Europe, they still have to fight hard for next season.
