We are not going to say that PSG was unlucky because they didn't reach the finals and lost it. From my own understanding, I feel that we are the ones giving PSG too much hype because they don't have a rival in their domestic league. We think that they are very strong, but they come to UCL and mess things up for themselves. PSG need more improvement in order for them to have the chance to win UCL.
There is no doubt that PSG is the strongest team in Ligue 1. PSG is able to perform very well in Ligue 1. The main reasons why PSG is able to perform well in Ligue 1 are that PSG's opponents in Ligue 1 are relatively weak. There is no team in Ligue 1 that has an experienced and strong squad. The most experienced and expensive squad in Ligue 1 is PSG and this is why we see PSG's dominance in Ligue 1 every season.
However, in the Champions League, we do not see a better performance than PSG. Almost every team in the Champions League is very strong. If you want to do well here, you definitely need an experienced squad, as well as an experienced coach. It is not possible to do well on the Champions League platform without an experienced coach and an experienced squad. PSG's coach is quite experienced. If Luis Enrique is given enough time and opportunity, maybe the next PSG team can do well on the Champions League platform as well.
