Victory on Torino on Sunday and the defeat of Inter Milan against Roma saw Napoli take control of the title race.
Conte said: “There are four more steps to take. We have taken the first, we are in front, now we know very well that we are taking on teams such as Lecce and Parma who are fighting to stay in the Serie A, then Genoa and Cagliari.
“It's all in our hands. We won with great determination, a team that was aware of its own strengths, and inevitably the crowd pushed us like the 12th or even 13th man today. Even going to the stadium was difficult because there were so many fans busy.
“They were enthusiastic, very determined and tried to pass on all their determination.”
“We had to find goals”
Conte admits that he does not work with a complete team and is happy with the way his players have responded to his tactics and system.
He also stated: “Looking at the team, we had to find goals, because it is not a team where many players offer double digits.
“It is therefore inevitable that you have to work hard and try to make the best of the resources at your disposal at your disposal. I think everyone in the group has improved. Seeing the first goal, (Andre) Anguisa had a great no-look assist for Scott (Mctominay) to score.
“We have worked very hard and see the fruits of that work. We have 74 points, with four rounds to go, I think we are now in the Champions League. Seeing where we started, that's remarkable. The credit goes to the boys.”
Conte added: “The Scudetto would be wonderful.”
