I think Psg is waiting for the Mbappe transfer to be clarified. If Mbappe leaves the team, they will probably sign Osimhen right away. Osimhen will surely be successful in Paris. The departure of Messi and Mbappe negatively affects PSG. Osimhen can be one of the important names to eliminate this negativity.
Osimhen was a top scorer in serie a last season. Playing in the french league will not so hard for him. It's very easy for osimhen to play in the farmer league. Serie a is far competitive compared with league 1. That doesn't make sense if osimhen will face difficulty in adapting league 1.
PSG is still waiting for mbappe to make a decision as soon as possible. IMO, money raised from selling mbappe to the al hilal which was around 300 millions can be used for various things. I remember that the rumor about PSG and vlahovic but it seems like that was just fake news.
Still waiting for the final decision for mbappe. Osimhen is not wanna leaving from napoli in summer. He may leave from there next year. Napoli has been putting big wall for him.
PSG may become the only club that can afford to buy him at this moment. Any party is still patiently waiting for the decision that's gonna come from mbappe. Some clubs have been anticipating it as well.
