I think the Napoli management is looking for a coach with much more experience than Spalleti in the Champions League where Napoli performed well honestly but not at the level that is expected from a team who dominated a big league like the Serie A.I think that Napoli management is not thinking of the Serie A to win it again although it is in their objectives,rather they are focusing to bring again the absolute glory of Champions League in Napoli,to the city of Naples who will make sure to burn it down again,even in a bigger amount than they did in the party for Serie A title.
Is it the right decision to fire Spalletti? My personal opinion is that Spalletti should be retained as Napoli's coach. Napoli showed great dominance in Serie A last season. And I want to give credit to their coach. Spalletti has got on very well with the players. He has a friendly relationship with the players. And so if Napoli changes coach it will take a long time for the team to stabilize. And so I would say Napoli's management should try to strengthen their squad instead of changing the coach. More talented players should be added to the squad.
I think it's almost impossible if Napoli's team management wants to find another coach and fire Spalletti, Napoli under Spalletti's coaching is good enough, they dominate Serie A and made it to the semifinals of the UCL this season, that's not a bad thing especially since Napoli is a team that just develop.
if Napoli wants to do even better in the UCL then give Spalletti more time and buy some top players, that's quite realistic in my opinion.
You are right. A change of coach cannot guarantee that Napoli will do well in the Champions League. Coach Spalletti's contribution to Napoli's good performance this season is undeniable. He has worked very hard to stabilize this team. And Spalletti's efforts have seen Napoli dominate Serie A this season. And if Napoli wants to do well in the Champions League next season, coach Spalletti must be given enough time and money. I believe that Spalletti will be able to strengthen the team even if the Napoli management supports Spalletti with sufficient funds.
