Since PSG won the Champions League last season. And they did not make any changes in the squad. So it is expected that we will see a stable performance of PSG in the next season. PSG has an experienced coach like Luis Enrique. But Real Madrid, Chelsea, Liverpool and City have all tried to strengthen their squad. Also Barcelona and Munich are also very strong. So the road to win the Champions League again for PSG is very difficult. Even my guess is that PSG will not be able to win the Champions League next season. They may be able to qualify for the semi-finals.
PSG just won their first Champions League title, left with the same players in the team, i expect them to be a difficult competitor but chances should be slim even if they will make the league difficult for other teams to progress, they might be kicked out during any stage of the finals before the main final. I have the feeling that if Barcelona can make it to the semi final, this time around might become the next Champions League winners, with their performance so far they deserve to raise the title.
After winning a title, a certain confidence usually builds up within the team. But it would be very foolish to continue playing with the same team. Because everyone else will understand their tactics and weaknesses. It would be very difficult for PSG to win the trophy twice at the same time.
But when it comes to Barcelona, I can say this. They were a very good team before and still are. Barcelona's game is never the same. They change their tactics again and again. They go out on the field to win perfectly. But it is not always the same. In all kinds of sports, luck is needed as well as skill. Football is no exception. But, this time Barcelona will try their best to make the trophy their own.
