Having many star players in a team sometimes does not always have a good impact, the proof is when PSG still has several star players such as Kylian Mbappe, Neymar Jr, Lionel Messi and Sergio Ramos but they still can't realize their dream of winning the Champions League title they are only able to win the domestic title when they have spent a lot of money so the presence of star players is not something that can be proud of by the club if the club cannot maximize its performance, precisely with high solidarity and good cooperation even without star players the club can perform as well as possible because they have the motivation to work together to realize their dreams not be selfish to be able to get individual titles only.
If people ask why PSG didn't win Champions League because they have Mbappe, Neymar, Messi and Ramos, I would say why they will beat beat Real Madrid when they have Courtois, Rudiger, Nancho, Carvajal, Rudiger, Militao, Modric, Valverde, Bellingham, Benzema, Vinicius and Rodrygo? 4 players can't beat 11 players.
PSG is only have few star players, while Real Madrid have eleven star players.
Paris Saint-Germain had spent a lot of money at the time and expectations were very high. The French were seen as one of the best teams in the world at the time. Now they have lost Mbappé and naturally they have weakened. However, despite this, they are playing very successful matches in the French League. I think they can show a similar performance in the Champions League. Also, it is almost guaranteed that they will be champions this year.
