Even I have to be agreed with you about this all but still this all is imagination because there is no doubt Spalleti done impressive job and achieve title after years with the leaves this job on high note and now doing Italian national duty, but we can be having same things with him which are hurting Napoli, and now they are down with poor performance and inconsistency as well now they are going to face AS Roma which is also badly down and having not fair chance for jumping into top four.
In last five game, Napoli fail to score any goal in three which is surely big problem for them, and they are surely needed to fix this if they want to have some honourable end of this season otherwise look like they could be badly down into this season, and then we will have no positive things for some years again.
Spalletti has shaped the character of the Napoli team as desired and it has been quite successful and Napoli was really a very strong team when Spalletti built this team but a risk for the team is that when the coach leaves it will be difficult for the new coach to be able to continue as is happening now and We can see several examples of other top teams that have been handled by a coach and then lost their character to the point that they could not be continued by another coach.
For now, Napoli may just need to be patient and start the process from the start and of course this will take a long time for them to recover because we will never see Napoli's performance again like what happened last season when coached by Spalleti. now everything is different.
