I really think if Osimhen does end up going to PSG he will certainly have some problems with Mbappe. Just a feeling. Personally, I do believe that he should go to other links.
I somewhat agree with you on this. In my opinion, if these two players are in the same team, a good harmony will not occur in that team. Because both football players are forwards who have high finishing features and prioritize scoring goals. Both of these football players are selfish by nature. If these two star football players play in the same team, I think there may be compatibility problems. Mbappe and Messi or Osimhen and Messi would be a good set, but Mbappe and Osimhen might be the wrong choice.
Probably PSG wanted to sign Osimen as a cover up should in case Mbappe sign for Real Madrid, I am very optimistic that Madrid will table another bid to sign Mbappe in the next transfer window having failed in their bid to sign him last summer, it very obvious Mbappe and Osimen can't play in the same squad at PSG thus Osimen will scrutinize whichever European club contract offer that comes for his signing especially clubs that will particularly guarantee a regular playing time and plays in UCL, next transfer window will very interesting and competitive for European club who will be jostling to sign Victor Osimen because of lack of quality striker in some major clubs e g Man Utd, Chelsea etc.
