The coach claims the team is in a positive place despite having lost three games in a row and revealed his Partenopei ambitions.
Though the Partenopei sit third in Serie A, they have lost their last three matches in all competitions including league defeats against Juventus and Parma.
However, Benitez feels his squad has made improvements during the season and believes spectators must focus on the bigger picture when it comes to assessing his team.
"This group of players is working very hard and is very concentrated, and this is why we made such a good start to the championship," the former Chelsea and Inter coach told reporters on Sunday. "The team are also in the Champions League with nine points, therefore I believe the balance is positive.
"We made a mistake in a difficult moment and were defeated in the match against Parma. This means we should be even more focused on the job we have to do."
Napoli brought in the likes of Gonzalo Higuain, Raul Albiol and Jose Callejon in the summer and Benitez, who took charge at the Stadio San Paolo in May, feels the club must be afforded time to grow off the field.
"When I was brought here, [club president Aurelio De Laurentiis] talked to me about his project to improve the club and this is what both of us want to do," Benitez said "We want to improve the structure and the club in order to attract important players and convince them to remain in this team. This is our idea."
Benitez envisions a future in which the club finds consistent success.
"I believe this is a unique opportunity for the club because they made a great job in the past and this allows Napoli to find important players able to make the difference and be competitive at high levels," he said. "We shouldn't be proud of the team because we win the championship once every 25 years. We have to be proud because every year the club has a certain level that allows us to be competitive in Europe.
"This is what we want to do, but this is of course a long path and sometimes we can make mistakes and we can be defeated, but this is the path we have to follow."
