I would say the way PSG have performed so well so far, if this trend continues, the team can do well in the Champions League this season. One important thing is that while this team has been dependent on Mbappe in the last few seasons, this season the team is not dependent on any particular player. PSG is now stronger as a team. This is why PSG is able to consistently perform well.
Luis Enrique managed to change the overall situation of PSG. PSG has managed to mitigate the weaknesses within the squad to a great extent. The team scored 13 goals in 3 matches and conceded 2 goals. So far we haven't found any weaknesses in PSG's squad. But looking forward to see how this team performs in the long run.
IMO, it's not really that the team depends on PSG. but rather making Mbappe a player who is able to score goals. he is a fast runner, has the talent and instinct to score many goals against the opposing team. therefore, his teammates on the field always try to find Mbappe and supply him with the ball, either in the form of assists or providing through passes so that he can run fast and score goals. usually, most coaches will take advantage of the advantages of their players' individual abilities. and as we all know, Mbappe has that talent and skill. currently, Paris Saint-Germains prioritizes group play. team cohesion and cooperation are more important points, but more than that, PSG still has other wingers who are able to run fast and dribble the ball very well. not infrequently, they pierce the heart of the opposing team's defense. this team is still a strong team, the difference is that they don't have a player who is able to score at least 20 goals in one season. As for Ramos and Kolo Muani, they have not been able to show their performance as well as possible. Enrique does not only rely on the system, but also explores the individual abilities of his players. Last season Barcola's performance was up and down, in three matches this season he was better than before. I have not been able to determine the weaknesses of Enrique's squad, because they have not found a strong team when competing. In the Champions League, ideally they qualify for the last 16.
