As for Osimhen, I am more confident that he will end up at PSG or Chelsea depending on the readiness in the clause given to Napoli from the 2 clubs rumored to be close to Osimhen at this time.
The possibility is very large but we also cannot be sure that it will happen because even though last season PSG boasted that they had prepared 150 million for Osimhen but that was an exception if Mbappe was sold, in fact for now Mbappe left for free so even though PSG is rich they still haven't taken any steps now.
As for Chelsea they are also still very possible but looking at what Chelsea are doing now that Enzo Maresca has bought several players now it seems like this is also becoming difficult unless Chelsea again burn their money for player transfers.
