Well the fault is all from Napoli because they actually set the price of this player so high that practically every club has shy away from the deal, if the price tag was place correctly I think osimien would have been in PSG by now but no, they had to just raise the bargain. But looking how dreadful their first game was I doubt if he would be in Napoli for too long because his contract isn't renew meaning no play I guess and Napoli currently now desperately needs some miracle to atleast get their campaign on track.
Its obvious that at some point maybe Napoli wasn't willing to let go of osimhen else what other better logical explanation do they have as to why such high price tag was placed on osimhen such that almost all the teams that did showed interest at some point lost interest and aren't coming back again. there was a time i learnt that one of the teams bidding for osimhen was ready to get him at 86k euros but Napoli wasn't willing to let go so he had to stay back and the danger of this is that since he's not willing to really stay at Napoli again, he's definitely not goin to preform excellently again and he will make sure to exit next season after the expiration of his contract. The current desperation of Napoli that they are suffering now is all their fault because they would have resolved this long before now if only they had don the lukaku osimhen swap deal.
