London :Cristiano Ronaldo was involved in all three of his team’s goals as leaders Juventus came from behind to beat 10-man Napoli 3-1 in a Serie A top-of-the-table clash to maintain their perfect start to the season.
Dries Mertens gave Napoli an early lead before Ronaldo provided a pinpoint cross for Mario Mandzukic to head in the equaliser and then set up an easy second for the Croat when his shot hit the post.
Ronaldo’s goalbound header also provided the third Juve goal for Leonardo Bonucci after Napoli had left back Mario Rui sent off for a petulant kick at Paulo Dybala.
AS Roma upset the form book with a 3-1 derby win over neighbours Lazio, who had won their last five games in all competitions, while Inter Milan beat Cagliari 2-0 to notch their third league win in a row.
Leaders Juventus, aiming for an eighth title in a row, have 21 points from seven games, six clear of last season’s runners-up Napoli. Sassuolo and Inter have 13 points followed by Lazio in fifth place on 12 and Roma in sixth on 11.
“Ronaldo is enjoying himself,” said Juventus coach Massimiliano Allegri.
“He has integrated very well. His precision in the passing moves is exceptional. I think this was his best match of the season.”
Piotr Zielinski fired against the post after six minutes as Napoli made a bright start and they were rewarded four minutes later.
Bonucci’s risky diagonal ball out of defence was intercepted by Allan who quickly found Jose Callejon and the Spaniard laid the ball off for Mertens to tap in.
Juventus needed a piece of Ronaldo brilliance to get back into the game in the 26th minute. The Portuguese twisted and turned past Elseid Hysaj and then dropped a perfect cross onto the head of Mandzukic who powered a downward effort past David Ospina.
Ospina then got down well to stop a Ronaldo free kick and did even better to block the rebound to prevent Juve getting a quick second.
