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.
