Andrea Pirlo got his coaching career off to a winning start as Juventus launched their bid for a 10th consecutive league title with a 3-0 win over Sampdoria on Sunday. Napoli defeated Parma as Lorenzo Insigne, Dries Mertens netted.
Swedish debutant Dejan Kulusevski opened the scoring after 13 minutes in Turin with Leonardo Bonucci adding a second on 78 minutes and Cristiano Ronaldo a late third.
Earlier, Napoli pounced on two defensive mistakes to win 2-0 at Parma in their opening match of the season as spectators returned to Serie A for the first time since March.
Dries Mertens and Lorenzo Insigne got Napoli's campaign off to a winning start with second-half goals shortly after club-record signing Victor Osimhen was brought on for his debut.
A smattering of fans, wearing masks and widely spaced apart, watched the game at the Stadio Tardini after the Italian government agreed to allow up to 1 000 spectators at matches from Sunday for the first time since the COVID-19 lockdown.
A cagey first half produced no real chances but Napoli came to life after Nigerian Osimhen, signed from Lille in the summer, was brought on in the 61st minute.
Two minutes later, Hirving Lozano crossed the ball into the area and Parma defender Simone Iacoponi headed his attempted clearance straight to the feet of Mertens who fired past Luigi Sepe from 15 metres.
Insigne struck the post from Osimhen's flick before Parma gifted Napoli a second goal. Lozano intercepted a pass out of the Parma defence, his shot was saved by Sepe but Insigne snapped up the rebound in the 77th minute.
