It is actually good to see that PSG signed a different kind of coach. Because so far with their usual strategies they haven't managed to make it to the Champions League title. Luis Enrique is about to change the usual strategies and build his own game for this team from now on. With a different game plan it is going to be interesting to watch PSG. If this works out for them with minimum number of issues then we might be likely to see PSG being competitive for the title for real this time.
I guess Luis Enrique would like to have a great star like Mbappe staying at least for this season. His contribution to the team would be vital in this run.
You may get a sense of what will happen from how each team performs, even though I am aware that it would be unwise for me to evaluate them or even assert that they cannot win the champion league title. Despite my belief that PSG will give it their all in the Champions League, I don't think they will succeed in taking home the trophy because there are so many other good teams who play far better than PSG does. psg is a very large team in league one, one of the best teams that frequently wins league 1, and they also have a good coach because the team consistently spent a lot of money to ensure that the team performance looked great. However, the upcoming champion league will be very competitive, so I don't think psg will win the champion league title next season.
Psg is in the process of acquiring a new player from various clubs, including Dembele from Barcelona. If Dembele joins the team, I think the team's performance will be excellent, but due to another rumour I've heard, Barcelona wants to trade Dembele and Rafhina for mbappe, and the Paris Saint-Germain wants to purchase only Dembele because mbappe wanted to play for Real Madrid. To prevent another issue from the team, I believe PSG needs to resolve everything before the start of the Champions League. This is because the current problem with the Mbappe to another team has turned into another one for the team.
