Yes, that seems to be the case. Napoli actually don't want to let go of their flagship players this season, because at least they have to maintain the title, that's why they set a very high price for Oshimen. Likewise Oshimen, he still feels at home and wants to be in Napoli. SO, PSG's hope of getting Oshimen seems quite small indeed.
Well, it will be very difficult to keep the Napoli title. I would say that the question is about the competitiveness of the club in the fight for a place in the Champions League. Nevertheless, the championship season at Napoli turned out so well and the stars were located in such a favorable combination that it is very difficult to expect that everything will be the same this season. Moreover, the main culprit of the miracle in the person of Luciano Spalletti left the club.
