Paris of Garmine has been trying for so much to win the Champions League for some seasons ago. They have spent money to bring in world class players but it didn't work for them. Even in the last Champions league when their 3 star men were available and they couldn't win the Champions League.
Checking the quality of clubs this season you will understand that so many clubs are in order and preparing more than PSG. So, this their season of disarray they will not achieve the CL trophy.
Last season, PSG were not strong at all. They could not even take the first place in the group losing it to Benfica! Of the 3 stars only Mbappe was really useful (Neymar at the beginning of the season, but when it came time for the decisive games, he was already blown away). If you look at the “brand”, then they lost to the “great” Bavaria, but in fact we all saw that Bayern was frankly weak last season. In fact, a weak PSG lost to a weak Bavaria. It was the end of their cycle, now we will see what the new team will be capable of.
