The 25th edition of the Italian Super Cup will take place in Beijing, China on Saturday, August 11 between last season's Coppa Italia winners Napoli and Serie A winners Juventus.
It promises to be an intriguing encounter and Mazzarri has confidence in his players to come out on top.
"The Supercoppa has been missing from Napoli for 25 years, so we strongly want to win it," he told Tuttosport.
"We won the first trophy of my management this year (Coppa Italia) and now, just a few months on, we want to continue winning.
"Success causes self-esteem to grow as well as bringing prestigious trophies. Juve also want to win it, but maybe we're hungrier than them."
Napoli finished fifth in Serie A last season.
