The two players who Antonio Conte wanted more than any others secured Napoli its second Serie A title in three years.
Scott McTominay scored with an acrobatic bicycle kick before halftime and Romelu Lukaku doubled the lead with a solo goal after the break in the decisive 2-0 home win over Cagliari.
Conte became the first coach to win the Italian championship with three different teams.
“Everyone contributed to this — but the coach most of all,” Napoli captain Giovanni Di Lorenzo said. “Napoli needed him to get back on top. He’s phenomenal.”
Comparing it to his three Serie A titles won at Juventus and one at Inter Milan — not to mention a Premier League title at Chelsea — Conte said it was “the most unexpected, the most difficult, and the most stimulating in terms of the challenge.”
