The Biancocelesti will be hoping to repeat the impressive performance seen in the 3-1 win over Inter, whilst Napoli are looking to return to their initial form this season, when they dominated Monza and Hellas Verona.
Both sides sit equal in the Serie A table, having picked up two wins and two draws each in their opening four fixtures.
The only player unavailable for either side is Napoli’s Diego Demme, giving Spalletti and Sarri all their options for the clash.
Lazio did not have a good time against Napoli last season, losing the away match 4-0 and the home game 2-1. Sarri has only ever beaten Spalletti once before, something he’ll be hoping to change tonight.
Confirmed Starting Lineups for Lazio vs Napoli:
Lazio (4-3-3): Provedel; Lazzari, Patric, Romagnoli, Marusic; Milinkovic-Savic, Cataldi, Luis Alberto; Felipe Anderson, Immobile, Zaccagni.
