What is happening to PSG is not a new thing, expectations and anticipations can most times cause some of these things to happen, after the won the champions league, a title they have long worked for, they got their morale pumped up high and probably felt they have been able to equate with top European teams forgetting that this could cause them some fall when they feel too comfortable at the top, best thing they should and can do now is to get back on improving and not allow the event of the loss continually tell on them.
PSG will face a lot this season, because there are already feelings at the top, and also the same amount in the top European teams, which will affect them a lot. Even though they are seen as the team that will do something good this season, I don’t think they will be able to perform any better, as there is a lot of expectation on them. If care is not taken, their performance might even go worse, as they might have some challenges even in their domestic league, which will make them have a worse season this season.
