Lorenzo Insigne enjoyed his historic two goals and two assists in a 4-3 win over Fiorentina, but warned Napoli “made too many errors.”
The captain contributed to four goals in a single Serie A game for the first time in his career.
“I am happy with the two goals, but the important thing was to win. We suffered a bit too much and will analyse the errors with the Coach, because I think there were many of them.
“It’s the first game, we had an intensive pre-season, but the important thing was to get the victory,” Insigne told Sky Sport Italia.
The Partenopei cannot disguise they are Scudetto contenders and will go head-to-head with Juventus next week.
“It’s true this is only Week 1, but wins help you keep on winning and we’ve got another tough match coming up in Turin.
“We’ve got to improve our defensive movements. I like this team, we have some great new buys, but fortunately the transfer window is about to close so we can all concentrate.
“It is a long season, we will try for the Scudetto, as we did last year and the year before. We need to focus on the details, get those right and then we’ll be up there.”
