Cristiano Ronaldo scored his first goals for Juventus as they beat Sassuolo 2-1 to continue their perfect start to the Serie A season.
Ronaldo had failed to score in his first three matches since a €100 million move from Real Madrid, but he came good in style as Juve won a fourth game in succession to remain top of the table.
In the 50th minute Sassuolo defender Gian Marco Ferrari could only head a Juventus corner onto the left post and Ronaldo was waiting to volley in a rebound from less than two yards out.
Ronaldo added a second 15 minutes later when he finished off a swift counterattack with a precise finish into the bottom right corner.
The five-time Ballon d’Or winner was denied a hat trick by a fine save from Sassuolo goalkeeper Andrea Consigli, while he also mishit a clear opportunity late on.
Substitute Khouma Babacar pulled one back for Sassuolo in the final minute.
Juventus, seeking a record-extending eighth successive Serie A title, are the only team still with a perfect record.
Juve midfielder Douglas Costa was sent off in stoppage time after spitting at Federico Di Francesco having become involved in a running feud with the Sassuolo midfielder.
Costa escaped with a booking for elbowing and then head-butting his rival as they tangled before the Sassuolo goal but was then sent off after video cameras caught him spitting at the same player in another altercation.
