Napoli, the reigning champions of Serie A, experienced another defeat, losing 3-0 to host Torino on Sunday. Goals from Antonio Sanabria, Nikola Vlasic, and Alessandro Buongiorno propelled the home side into the top ten. Torino opened the scoring just before halftime following a well-organized attack when a free kick taken by Ivan Ilic deflected off teammate Duvan Zapata and fell to Sanabria, who scored. Shortly after the start of the second half, Napoli was reduced to ten men when Pasquale Mazzocchi was sent off for a strong tackle just five minutes after his debut. Torino took advantage of the situation, with Vlasic and Buongiorno scoring two consecutive goals to secure the win for the team. The reigning champions, who have won only once in their last six league matches and are lagging 20 points behind leaders Inter Milan after the first round, hope to return to the right track when they host bottom-placed Salernitana next Saturday.
