Napoli president Aurelio de Laurentiis believes title rivals Juventus have an advantage this season.
De Laurentiis says Juve's lack of European football will work in their favour.
"Napoli, in my mind, need to always be a team that grows," the movie mogul declared. "However, there will always be great performances and those like we gave against Parma.
"I expected games like that. They had more hunger than us, whereas we already had our minds turned to the Champions League.
"That's why Juventus have a great advantage over the other Scudetto candidates this season. They can focus on just the League given that they are not involved in Europe."
