Paris Saint-Germain will surely win the final against Chelsea. I know it's a given, but it's normal for it to happen. They currently have the best team around and can boast a bench that could be another top club starting lineup, so unless they make mistakes, victory is in their pocket.
Welll... We all know that PSG's squad is very strong. And the bonding between the players is also very strong. Before qualifying for the final, PSG team has performed well and won against giant teams like Atletico Madrid, Bayern Munich and Real Madrid. The dominance of PSG players was visible in every match.
Still, I would say that PSG will have to play very carefully if they want to win the final. Chelsea is a team that is capable of playing well in the final. In the 2020-21 Champions League final, we saw that Chelsea won the title by defeating the strongest team Manchester City. Chelsea was quite lucky in the final. So PSG will definitely have to perform very carefully if they are interested in securing the FIFA Club World Cup title.
