Cristiano Ronaldo missed a chance to score his first Serie A goal for Juventus but the Italian champions kept their winning momentum 2-1 at promoted Parma on Saturday with goals in either half from World Cup stars Mario Mandzukic and Blaise Matuidi.
World Cup winner Matuidi bagged the decisive goal on 58 minutes after Croatia's Mandzukic, a finalist in Moscow this summer, had scored after just two minutes in Emilia Romagna.
New Parma signing Gervinho -- back in Italy after two years with Chinese club Hebei China Fortune -- pulled one back after 33 minutes for the hosts who have returned to the top flight after three consecutive promotions following demotions for bankruptcy.
Ronaldo is yet to score but the seven-time reigning Italian champions are on maximum points after winning all three of their games this season.
The 33-year-old five-time Ballon d'Or winner missed a chance to open his account after 26 minutes when his powerful header was just wide, and spurned another chance ten minutes into the second half.
"Cristiano had a good game, he made himself available, but it was a moment when the ball did not bounce back in the right direction," coach Massimiliano Allegri said. "I'm happy with what he's doing."
Matuidi said: "He had a great match but he had no luck. He's trying hard to score, he's going to be a little annoyed because he's still hungry to score, but we're going to help him."
- Nainggolan gets Inter off mark -
Earlier Radja Nainggolan scored on his debut as Inter Milan claimed their first three points of the Serie A season with a 3-0 win in Bologna.
Nainggolan missed the first two games of the campaign with injury following his summer move from Roma.
But the 30-year-old Belgian midfielder made his mark on his league debut, opening his and Inter's account at the Stadio Dall'Ara after 66 minutes.
Italy midfielder Antonio Candreva and Croatia's World Cup runner-up Ivan Perisic added two quickfire goals in the final ten minutes to seal all three points.
The win gives Luciano Spalletti's side four points from three games, equal on points with Roma who lost 2-1 at AC Milan on Friday. Filippo Inzaghi's Bologna are stuck on one point, without a single goal scored in three games.
"There were three beautiful goals and the team shook off the tension after the opener," said Spalletti.
“We should have been a little more inventive, creative and had more quality to pick the lock earlier. But as we went on we wore them down.
"Some of our players need to find their fitness levels, as you need quality and names to win, but also hard work and sweat on the pitch."
Inter captain and striker Mauro Icardi tried, unsuccessfully, to shake off a muscle strain by warming up before being forced to watch from the stands, along with Lautaro Martinez.
It left Keita Balde as Inter's sole striker, but with Nainggolan, Matteo Politano and Perisic in support.
Perisic nodded into the side-netting early with Roberto Gagliardini also firing over for the visitors before Bologna threatened, Filip Helander's header cleared off the line by Inter goalkeeper Samir Handanovic.
Nainggolan missed a chance to open the scoring just before the break with a powerful half-volley from the edge of the box flying over.
But the Belgian made no mistake after the break, controlling Politano's cross to fire past his former Roma teammate Lukasz Skorupski.
Candreva replaced Keita on 79 minutes and three minutes later turned in a low cross from Perisic for his first goal in over a year and a half, the Croatian sealing victory two minutes later.
