Napoli was great this season but there is no guarantee that they will be great next season as well. There is a potential that they could be good, but there is a potential that they may not be that great at all as well. We should be careful about what's going to happen and if the transfer season starts and we get to see who leaves and who comes in, we can make a better prediction.
All of their players have someone going after them and that means a lot of money could be earned from the sales but that doesn't mean that they will end up doing anything important, it might be great or it might be hard but in the end we are not going to end up with anything good if they sell most of their players so they need to start focusing on who they can get instead.
The 2020/21 season Inter dominated a lot but in the following season Milan won. Likewise, in this case, it was Milan in the 2021/22 season that managed to frustrate Inter and they were very chaotic this season so that Napoli played very well and immediately won the title without any significant resistance.
To be honest for this I even doubt they could be like this. It is possible that some players will leave, on the other hand the coach has also confirmed that they will have great inconsistency if they cannot fix this.
