I think it's difficult for Napoli to defend the Scudetto even though they are very ambitious for it. Spalletti's departure is a clear sign that the Partenopei have lost their best instructor.
Osimhen is Napoli's mainstay striker but in my opinion now is the right step for Napoli to sell him because at the moment he still has a fairly high price on the market. It's useless if it is maintained because if Osimhen is unable to maintain his performance next season. I think selling Osimhen was part of an investment move for Napoleon.
your statement seems to contradict what you say yourself. you doubt Napoli can't defend the Scudetto but you think selling Osimhen is the right move? lol
Are you aware that Napoli needs Osimhen to keep holding the Scudetto because without Osimhen there are no reliable players even though this requires solid players from all players but Napoli only has Osimhen to help win the Scudetto title in the summer.
there is little hope for Napoli even though Spalletti left this team but if the new coach is able to provide almost the same strategy I am sure Napoli can still dominate Serie A.
