The agent of Napoli captain Paolo Cannavaro has hit out at the team's mentality.
Napoli were held 0-0 by Sampdoria on the weekend.
"In order to aim for the Scudetto, Napoli would have to win them all, starting from Udinese on Monday," agent Enrico Fedele told Radio Crc.
"As a fan, I hope Napoli can win the title. As a professional in the football world, I say this is just a dream.
"The truth is the Azzurri have to lock down this second place. That would already be a great success and part of their progress.
"They lack that winning mentality and the only way you earn it is over time. Don't forget those who are accustomed to travelling at a certain level do not feel altitude sickness. They have done so well up until now due to their hunger."
