Dusan Vlahovic fired Juventus to a comfortable 3-0 win over Sassuolo with a brace in Monday's Serie A opener while Victor Osimhen was racially abused by Verona fans in a thumping 5-2 win for Napoli.
Serbia forward Vlahovic put Juve two ahead just before the break from the penalty spot after being fouled by Gian Marco Ferrari, and ended the match as a contest following a smart Angel Di Maria pass six minutes after the restart.
Argentina winger Di Maria had set Juve on the road for a low-key win with his first Serie A goal, a miscued volley in the 26th minute of his debut after arriving as a free agent this summer.
"It's really a great feeling and a pleasure to play with such a great player," said Vlahovic of Di Maria, who was substituted with a thigh injury midway through the second half.
"I should thank him for the assist he gave me. I'm very happy and hope to be on the end of others. I think we can work well together."
Massimiliano Allegri's side were missing returning hero Paul Pogba, out with a knee injury until next month, and injured starting goalkeeper Wojciech Szczesny.
However Allegri gave Filip Kostic his Juve debut off the bench, a new face who along with the excellent Di Maria could rejuvenate a sluggish team who came up against the weak resistance at the Allianz Stadium.
