Insigne isn't assured of a starting shirt in Naples, but he's already done enough this season to win his first full cap for Italy.
"Boss Walter Mazzarri was clear with me from the start," he said. "He said that I would be the first choice behind the three champions of Edinson Cavani, Marek Hamsik and Goran Pandev. And that is how it has been.
"I did a lot in pre-season training and I think I earned my place in the Napoli squad."
