Cristiano Ronaldo scored his first competitive goals for Juventus on Sunday, with a second-half double by the Portuguese star giving the Italian champions a 2-1 Serie A win over Sassuolo to make it four victories from as many games.
The 33-year-old tapped in from barely a yard out after a goalmouth scramble on 50 minutes, and added a second 15 minutes later following a counter-attack orchestrated by Emre Can as the defending seven-time champions moved three points clear of Napoli.
Juventus are the only unbeaten side this term after Napoli inflicted a first loss on Fiorentina on Saturday with a 1-0 win ahead of next week’s Champions League trip to Red Star Belgrade.
Sassuolo are now third with seven points.
Five-time Ballon d’Or winner Ronaldo was the star signing of the summer transfer period, arriving amid great pomp and ceremony following a 100-million-euro ($117 million) deal from Real Madrid.
Bolstered by five-time winner Ronaldo, Juventus begin their quest for a first Champions League title since 1996 at Valencia on Wednesday.
The Turin giants also won the European title in 1985, but finished runners-up twice in 2015 and 2017 under current coach Allegri.
