I think they shouldn't rush into the transfer. Mbappe is an important player, but his absence can be filled by a player somehow. Here, PSG observers and technical staff will have to work overtime to choose the best. Mbappe is gone, but the next name will have to look no further. A difficult period begins for PSG. They should select the best player and add them to the team and play better next year to lift the UCL cup, which is their main goal.
Yes, dont panic. PSG isnt only Mbappe, a world-class player. With finances and appeal, they may recruit great talent. The club can demonstrate its stability. Its exciting to see how and who they hire. It could be pivotal. The team may improve or a new star develops. What about the UCL - thats the end goal? Missing Mbappe is a blow, but they can still contend. Perhaps it will make them play smarter and more strategically. Soccer is a team sport, and PSG has many outstanding players.
For some reason, I actually firmly believe that Mbappé leaving PSG is probably one of the best things if not the best thing that has happened to PSG. We all know that he was not playing to make PSG a great team. He was in PSG for the money and the influence. I would not be surprised if Macron had actually offered him half of France and the Eiffel Tower to stay in the PSG team

.
But he finally did choose Real Madrid which he should have done ages ago. What I found to be a little amazing he attracts PSG to get more money out. And he just got away with it like that. The only thing he probably suffered is not getting as much salary as he could have gotten if he went to Real Madrid earlier. Remember when Real Madrid offered 220 million for him? He could have gotten more salary at that time in Real Madrid compared to what he is getting right now. But we all know that can be fixed at any time with a new contract.
Why I say it is a good thing for PSC because they will not have to build a team around someone who does not want to play for themselves in the first place.
