Nowadays there is talk that Osimhen could be transferred to Chelsea. Napoli could partially fill Osimhen's void with Lukaku. I think such a swap between the two clubs would make sense. Both teams would get what they need in such a deal. Anyway, I don't think Napoli can keep Osimhen any longer. Napoli are a waste of time for Osimhen. He should play for better teams for his career. And Lukaku can have his last big team experience with Napoli. If he doesn't get good stats at Napoli, he will be forced to choose between a salary cut or a move to the Arab leagues.
As we have things in last season between Napoli and Victor Osimhen there were chances he is not going to stay here for more season so now most chances things will be workable for the Chelsea and Napoli because Antonio Conte was looking for Lukaku and Napoli were looking for better exit of the Osimhen now we will have swap which helps both clubs to settle things without any big hassle.
If we have things as they are looking for in future surely we will have all settled without any problem and both clubs will be able to have their desired money as well Lukaku surely needs to give his best because if he wants to keep things at the top this is important for him otherwise we will have this Belgium star in Arab League which could be not good deal for him in the future.
