Napoli don't need to make big changes to their squad. Filling the places of the players who have left will be enough for them to be competitive for the Serie A title once again. For example they have lost a very important member in the defense line. Kim Min-jae has signed for Bayern Munich officially as you know.
They had better shift their focus to finding another solid and credible defender in his place. Other than that they should do their best to not lose other two crucial players who are Osimhen and Kvaratskhelia. As long as the squad integrity is maintained highly it will all be up to Rudi Garcia's creating a strong bond with the team to go for success.
Exactly! I think like you too, Napoli must absolutely cover up for Kim's absence in their defence. Rudi Garcia knows the Italian championship well and I think he will show good performances with Napoli this season, they have to defend the title of Italian champions moreover, but above all Napoli must also compete in the Champions league and therefore some reinforcements in midfield will be needed
