I am more interested when Osimhem joins the English league compared to other leagues because if he is able to maintain the best playing form then in the English league it will be easier for him to achieve the best career. Chelsea is not at all a good place for him to come to now because the club's condition is very unstable and vice versa with Man United, but compared to Chelsea Man United is much better for Osimhem. If there were other clubs interested, maybe I would agree that he would be better off playing there, but so far not many clubs are willing to pay Osimhem a high price.
If players prioritize money then PSG is the place because there they can get everything like Mbappe, but talking about individual careers it is completely difficult for them to achieve this because PSG is only able to dominate the local league. If a player wants to have the best career then he must consider joining a certain club because if they are wrong they will actually bury their dreams of achieving the best career.
Its not easily to predict about Victor Osimhen future will play for Premier League teams or he will accept offer from PSG or any La Liga teams interested for signing him. Depend on how much salary payment offer for each teams are interested for him and how much transfer fees release by Napoli filtering the higher bid offer will be prioritize to acceptable.
Indeed have several Premier League teams such as Chelsea and Manchester United are interested for signing Victor Osimhen but both of teams not give official bid offer. Actually Napoli will prefer with teams want to pay more excited fees transfer and I think Manchester United get difficult with spending much money fro fees transfer and more close opportunity with PSG has higher bid offer exactly their position after leaving by Mbappe.
