PSG did not underestimate their opponents, they lost even though they played with their good players. Of course, the lack of some players could have created a different atmosphere, but it would not guarantee that PSG would come out on top in this game.
PSG did not make many changes to the squad. However, in the match against Atletico Madrid, Ruiz, Vitinha and Neves were in the midfield. We did not see Ruiz and Neves in the starting XI in the last match. We also saw Marquinhos outside the squad. However, PSG's attack remained unchanged.
Although this squad won 4-0 against Atletico Madrid, they could not score a single goal against a team like Botafogo. PSG's players are trying hard. PSG's players were able to make a total of 16 shots. But even then, PSG could not break Botafogo's defense. Botafogo was quite tactical in this match. After getting a 1-0 lead, they kept their defense strong and wanted to end the match 1-0. And they managed to achieve this.
In my opinion, the European teams are tired and also not very motivated with this competition, mainly because it is transfer season. Many players will save their physical condition to avoid injuries and not being signed. In other cases, they will save themselves because the next season starts in August.
But I have no doubt that the American teams have great potential. They are strong, they play well when they are facing European opponents, but when they play against each other, they play so badly that I cannot watch the games involving two American teams against each other.
