That's the game of football. Many sports commentators consider Paris Saint-Germain, with its squad featuring Messi and Neymar, to be among the most serious contenders for the Champions League title. And let's not forget that Mbappé was also on that team. While such a strong Paris Saint-Germain couldn't win the Champions League title, the first year Mbappé left the team, when everyone expected a decline in performance, Paris Saint-Germain won the Champions League. That's why I love the UCL. It's truly difficult to predict.
Most times it's not about the names of the personalities in the squad but about teamwork, concentration and a positive mentality, with all these in place nothing can stop a team from progressing, when PSG had all the big names, they couldn't perform very well because having big names doesn't necessarily mean you will win the UCL, and perhaps they didn't have a good coach who could organise the team and turn it into a winning side.
