Osimhen is the most ideal for PSG to bring in the summer transfer window. In my opinion, he is more ready to become the main striker who is relied on to be their goal machine. Because, Osimhen is more ideal if he is under the guidance of Luis Enrique. It does not mean that Gyokeres is not less great than Osimhen, after all, his name is currently soaring as a pure striker. But I'm not sure if PSG will bring him in, although I could be wrong in this matter. Unlike Osimhen, he had intended to join PSG, it's just that the French League giants were not willing to pay the transfer price that Napoli wanted at that time. Well, as you said, Osimhen's transfer value is currently decreasing. If he no longer wants to return to Napoli after his loan period ends with Galatasaray, there are not many options for Napoli to find the ideal deal so that they don't loan him out again and end up with a free agent player. and if Osimhen joins PSG next season I am pretty sure they will be a strong team again in the Champions League, and in this competition the PSG players available are also quite productive in terms of scoring goals unfortunately their performance is the opposite in the Champions League. by the way, most likely Paris Saint-Gemains will still be the champion in this competition, because their probability is very high. in the Champions League, I am not too sure how they will be able to qualify for the next phase.
If PSG is still confident enough to improve their performance, especially their attack line by bringing in Osimhen it should be quite good. But the problem is Napoli still has Osimhen, their fate is not going to be together again after some disputes. Osimhen only wants to go to a team that is willing to pay the agreed fee.
I think bringing him in is a good move, but it all depends on how serious they are about bringing him to PSG.
