Oshimen is already very comfortable in Napoli, so it's impossible for him to leave easily. His career at Napoli has been very good, with a salary offer of €5,450,000 annually, which is quite a large value with the facilities that Oshimen got while still contributing to Napoli.
This really strengthened his position at Napoli not to leave the club that had made his name big. However, the two of them provide mutual benefits to each other, a symbiosis of mutualism. As long as they both value and optimize all their abilities, it will not be easy for Oshimen to leave Napoli.
However, if in this transfer market PSG really loses Mbappe, it is likely that PSG will move quickly to try to redeem Osimhen from Napoli. In fact, the Napoli boss himself said about Osimhen and PSG.
Actually there are several names that are alternatives to replace Mbappe at PSG, indeed one of them is Oshimen from Napoli. However, several other names also appeared, such as Vlahovic, Kane, and Hojlund. However, this is still a rumor that is being linked. because, there are indeed many other big clubs who are also conducting discussions and bidding on these players.
Of course PSG also want a very good replacement at their club, but they must also be aware and understand very well that they will definitely not get a new player like Mbappe.
