Giovanni Trapattoni claims Napoli are capable of winning the Scudetto this season.
However, the former Italy coach feels the expectancy could become too much for the Azzurri.
"There is no patience in the south, even though it is the club with the best long-term plan that wins out," Trapattoni told Il Mattino newspaper.
"Every time Juventus were beaten in Europe, Boniperti would arrive and reassure us it wasn't a tragedy, so there was no need to cry and wail over it.
"We won at Juve because, unlike places such as Napoli and Roma, we did not experience those huge leaps from enthusiasm to despair.
"They continue to make the clubs in southern Italy unique in the world, but can also be frightening. You can't win a game without being treated like a prophet or lose the next week and hear your job is hanging by a thread.
"I was often called to Napoli, first as a player and then a Coach. I am enchanted by the city, but the pressure created around the team can really affect performances."
