Napoli announced the squad for their initial pre-season training, including both Insigne brothers.
The team will begin work on Thursday at the Dimaro camp, though obviously the players involved in the knockout stages of the World Cup will arrive later.
Rafa Benitez will be working with both Insigne brothers, as Roberto is brought back from his loan spell to partner older sibling Lorenzo.
The 20-year-old spent last season in Lega Pro with Perugia.
Goran Pandev is also included, despite strong reports he has been told to find another club this summer.
Napoli squad: Rafael, Colombo, Rosati, Contini, Maggio, Mesto, Britos, Gamberini, Koulibaly, Radosevic, Jorginho, Donadel, Hamsik, Pandev, Callejon, Lorenzo Insigne, Roberto Insigne, Duvan Zapata, Dumitru, Maiello, Ciano, Lasicki, Luperto, Anastasio, Romano, Fornito
