After three games without scoring, Cristiano Ronaldo grabbed a brace against Sassuolo, but Juventus team-mate Douglas Costa was sent off.
Cristiano Ronaldo opened his Juventus account with two second-half goals in the Serie A champions' 2-1 victory over Sassuolo, but substitute Douglas Costa's red card for spitting cast a shadow over the match.
Unspectacular though it may have been, the five-time Ballon d'Or winner's first goal delivered a palpable sense of relief around the Allianz Stadium, where the hosts had struggled to create chances against their in-form visitors.
His second smacked of a man settling into life in Turin, the former Real Madrid star coolly drilling the ball home after 65 minutes.
