Paolo Cannavaro says everyone at Napoli aren't getting carried away after their superb start to the season.
The defender said: "We couldn't have asked for a better start. But we know it's early days and we must stay grounded.
"The key is the foundation we have. The building blocks of this team have been together for many years. We've had some great quality join us and the secret is how well they have integrated into the squad."
