Yes, maybe these 2 wins make everyone believe that Napoli has returned to trying to be consistent, but I don't believe that Napoli will return to having stable performance because if you say this is a good start, but for me this is the start of a bad thing for bettors at the moment. looks very strong but against Torino it only ends in a draw or even a loss.
It can be their start of recovery and run faster to try participating in top four which currently is far of their hands. Though it is not easy to catch other above clubs but Napoli are on a good form to fight for that target.
Beating Juventus is a very strong performance of Napoli to strengthen their confidence for coming matches. Juventus don't have good form but beating The Old Lay in Serie A is never easy.
As long as Napoli can't get consistent wins like last season I will never believe in Napoli or even shifting Bologna's position seems very difficult because Bologna's performance is much more consistent and on the other hand Napoli will have the pressure of competing against Barcelona in the CL competition and also the pressure of the match. against Inter Milan.
Bologna don't have experience to compete for top four position and potentially they will have problems to maintain their good performance in future. It will give chances to Napoli and some other clubs like Roma, Atalanta. Napoli can not control how Bologna play but they can control their performances. It is what they must focus on first and wait for green light from Bologna, Roma and Atalanta.
