Andrea Belotti off the mark with scissors kick in Torino win

An eventful match also saw two penalties over-turned -- one for each side -- after consultations with the Video Assistant Referee (VAR).

Belotti, who scored 26 league goals last season and is one of the hottest properties in Italian football, opened the scoring in the 45th minute with a truly outstanding effort.

Nicolas N’Koulou flicked the ball over a defender, slipped it to Lorenzo De Silvestri who sent over a long cross to the far post where Belotti, with his back to goal, launched himself into the air and connected with a perfectly-executed overhead volley.

The 23-year-old Italy forward also set up the third when he slalomed through the Sassuolo defence for Joel Obi to score in the 88th minute. Adem Ljajic had added the second minutes earlier.

Torino were awarded a penalty just before the hour for handball by Paolo Cannavaro but the referee changed his mind after consulting the VAR and deciding that it was accidental.

Sassuolo were also awarded a penalty which was then revoked after the VAR spotted an offside late in the game.

Milan, who have won their first five games of the season in the Europa League and Serie A, took an early lead at San Siro when Patrick Cutrone tapped in Suso's wicked cross at the far post.

But Cagliari would not lie down and Joao Pedro equalised in the 56th minute after Milan lost possession while trying to play the ball out of defence.

Suso, one of only three survivors from last season in the Milan starting line-up, restored their lead by curling in a free kick with 20 minutes left.

Napoli fell behind to a 15th minute header by Bryan Cristante at home to Atalanta and, despite playing with their usual panache, struggled to break down the visitors.

Piotr Zielinski finally levelled with an unstoppable shot in the 56th minute and they turned the game around five minutes later when Allan's chipped pass was headed on by Lorenzo Insigne for Dries Mertens to volley in at the far post.

Marko Rog finished off a well-worked move for the third in the 87th minute.

Gianluca Caprari and Fabio Quagliarella, from a penalty, scored twice in a three-minute spell in the first half for Sampdoria, who survived several scares after Milan Badelj pulled one back early in the second half for Fiorentina.

Promoted Spal won their first game when a stoppage-time goal by Luca Rizzo sunk Udinese 3-2 after the visitors had clawed back a two-goal deficit, with Cyril Thereau equalising from a penalty in the 87th minute.
