Napoli boss Walter Mazzarri is confident his players will hold their nerve in the battle for a top four finish.
The Azzurri have even been mentioned as an outside chance for the Scudetto.
"I think that this season the general standard is quite high in Serie A," said Mazzarri.
"My Napoli's objective is to not get big-headed and try not to have vertigo near the top of the table, but I'm certain we're not suffering from that.
"We are aware that sooner or later the quality of the squads will probably shine through but, like Palermo and Lazio, we can hope that we'll cause an upset."
