MILAN, Oct 7 (Reuters) - Two stunning goals from Adam Ounas and Lorenzo Insigne gave Napoli a 2-0 win over Sassuolo which kept them second in Serie A on Sunday.
Carlo Ancelotti’s team got off to a flying start when Ounas scored his first-ever Serie A goal after three minutes.
The Algerian intercepted a backpass with his chest, flicked the ball over a defender and then met the ball with a half-volley which he fired past Andrea Consigli.
Not to be outdone, Insigne ensured three points in the 72nd minute when he collected a pass on the edge of the area and fired a curling, dipping shot into the top corner for his sixth goal of the season.
Napoli have 18 points from their eight games — six wins and two defeats — and are six behind leaders Juventus, who maintained their 100 percent record with a 2-0 win at Udinese on Saturday.
Sassuolo had Rogerio sent off late in the game for a high challenge on Jose Callejon deep inside the Napoli half.
AC Milan striker Gonzalo Higuain scored two first-half goals to set his side on their way to a 3-1 win over bottom-of-the-table Chievo who remained winless.
Giacomo Bonaventura added Milan’s third and 39-year-old Sergio Pellissier pulled one back for the Flying Donkeys who are stuck on minus one point after having three deducted for accounting irregularities.
Lazio bounced back from last week’s derby defeat against AS Roma by beating Fiorentina 1-0 with a first-half goal by Ciro Immobile, taking them to third in the table (15 points).
Genoa forward Krzysztof Piatek maintained his record of scoring in every Serie A match for his new club although it was not enough to prevent them losing 3-1 at home to Parma.
The 23-year-old put Genoa ahead with a looping header after six minutes, taking his tally to nine for the season.
It also meant the Polish forward has scored in all seven league appearances for Genoa since joining from Cracovia for a modest four million euros ($4.61 million) in the summer.
However, despite missing forward Gervinho, promoted Parma hit back with goals from Luca Rigoni, Luca Siligardi and Fabio Ceravolo in a 15-minute first-half spell to hand Genoa a first home defeat of the season. ($1 = 0.8679 euros) (Writing by Brian Homewood, editing by Pritha Sarkar)
