Napoli continued their 100 percent start to the season and stretched their lead at the top of Serie A to two points with a 3-0 win over Cagliari at the Stadio San Paolo on Sunday.

Marek Hamsik handed the hosts an early lead by scoring his first goal of the campaign with a low, angled shot in the fourth minute.

Top-scorer Dries Mertens then netted his ninth goal in all competitions this season by slotting home from the penalty spot five minutes before the interval.

Kalidou Koulibaly rounded off the win with a close-range finish two minutes into the second period.

Second-placed Juventus had started the day on the same number of points as Napoli but lost their perfect Serie A record when they were held to a 2-2 draw away at Atalanta
