That regret has been forgotten by PSG and building a team that is more prepared to face the challenges coming next season and forgetting Mbappe. An experience that Enrique has to face to build a team which initially relied on star players and now he has to be pressured to be able to bring PSG to compete strongly in domestic leagues as well as in major competitions without relying on a star player like Mbappe.
It's a good time to build a team with young players or build new talents from recruiting young who can contribute in the long term and it's one of the best ways than spending large amounts of money on star players who can't last long and also give big losses. Nasser Al-Khelaifi seems to have already realised that building teams with star players won't give you a reputation in the longer term and building teams of reliable young players better guarantees a better future for the team.
Kylian Mbappe departure to Real Madrid was a major blow to PSG, who were always negligent in dealing with situations they could not control. Kylian Mbappe seemed to continue to feel comfortable, but after all this drama culminated, PSG finally had to accept the bitter reality and had no anticipation since the discomfort shown by Kylian Mbappe. PSG was certainly in a difficult situation from the start, even though its finances were adequate, if it didn't have good management the results would be very messy. In Ligue 1 this club will be fine, but in the UCL competition without a striker who can fill Mbappe seat, there is no guarantee that this club can survive any further. The transfer market is still open and until now Osimhen is still in an unclear situation, in my opinion PSG have to gamble by buying Osimhen to find out whether he can be the right person or not. That's the only way PSG can minimize poor performance in the UCL next season.
