Juventus were confirmed as Serie A winners for the seventh season running following a goalless draw with Roma.
Napoli had effectively handed the title to the Bianconeri after they were held to a 2-2 draw by Torino last weekend, which left Juve all-but mathematically guaranteed another crown.
Needing just a point at Stadio Olimpico, Juventus picked up the draw required to confirm a 34th Scudetto.
Roma, who had Radja Nainggolan sent off in the second half for two bookable offences, were already guaranteed a Champions League place after Inter Milan lost at home to Sassuolo on Saturday but they extended their advantage over rivals Lazio in the race for third to two points.
Napoli recorded their first win in three games with a 2-0 success at Sampdoria.
Polish forward Arkadiusz Milik struck from distance with 18 minutes remaining, with Raul Albiol heading in a second after 80 minutes.
Earlier Lazio had missed the chance to cement their Champions League place after needing a late goal from Sergej Milinkovic-Savic to draw 2-2 at relegation battlers Crotone.
