Napoli sitting 4th and they're determine to claim first but I don't see that happening anytime soon because they have challenging rivals to play against. Napoli president, Aurelio de Laurentiis will not blame the new coach if his team doesn't stand the gigantic energy in forthcoming games. Napoli new coach, Walter Mazzarri can only survive if he's able to withstand the pressing pressure from these elite teams by making defensive tactics. Napoli are defending Champs and I know winning games wouldn't be complicated for them specifically against average teams.
They now have a new coach who is supposed to be better than the forma so I think letting him have some time and seeing what he can do with the team is what most persons are doing now, let's see if he will help them achieve their dreams of been at the top of the table soonest or he will be a set back in the mean time.
Personally I think changing coach at this time will have some effect negatively on the team until after awhile when they might have got used to the coach and maybe the coach too have gotten use to the players aswell. By January I think he will be making some needed transfer to help strength the te and get the desired players he could work with to achieve that he aims to get before the end of the season but getting to the top of the table will take them some little time definitely.
I know that the management and fans of Napoli aren't okay with the current position of the club in the Italian Serie A table and that's one of the reasons why Rudi Garcia was recently sacked by the club and Walter Mazzarri hired as his replacement but that doesn't guarantee that the reigning champions of Italy are gonna gonna automatically start winning games that'll help them overtake the other clubs and return to the summit of the league table.
The new manager will need sometime to understand the level of performance every member of the squad can actually deliver and then find the best playing pattern that'll bring out the best from players.
