Changes, changes, and more changes. Carlo Ancelotti will continue to work the same way he has since the beginning of the season. His Napoli, who will face Inter later today, will be different from the one last seen against Spal. The 4-4-2 seems the basis to work on though.
Meret shouldn't play despite his good game against his former team Spal. Ospina should replace him and be the one to face Icardi. Regarding the defense, Maksimovic (favorite above Malcuit and Hysaj) should be the right fullback, with Ghoulam on the opposite side and Albiol - Koulibaly in the centre.
Allan is back for Ancelotti's midfield and should play with Hamsik by his side, and Callejon as the right midfielder. For the left side position, Ruiz and Zielinski are playing their chances with the Spanish midfielder most likely to start the game. Finally, for the attacking duet, Milik has better chances to start the game alongside Insigne than Mertens.
Probable formation Napoli (4-4-2): Ospina; Maksimovic, Albiol, Koulibaly, Ghoulam; Callejon, Hamsik, Allan, Ruiz; Milik, Insigne.
