After almost six goalless hours, the former Real Madrid man opened his account with a double to help his side to another victory
The 33-year-old failed to find the net in his first three Serie A matches following a €112million transfer from Real Madrid in July before finally breaking his duck on Sunday.
Ronaldo praised the way Juventus broke down a stubborn visiting defence and admitted that his failure to find the net had been starting to play on his mind.
“I’m very happy, we started well,” he told Mediaset.
“Sassuolo defend well, but we put in an intense performance and deserved to win.
“I really wanted to score these first goals and I’m happy to have found the net.
“This is football. The important thing is that the team wins. Obviously, I was a little tense with all the talk of Real Madrid and not scoring, but I thank my team-mates for supporting me throughout.
“I knew that I was working well and it was only a matter of time. I am adapting well to Italian football.”
Juventus travel to Valencia for their opening Champions League fixture on Wednesday and Ronaldo is looking forward to playing again in a competition he has won three times in the last three years with Madrid.
Manchester United and Young Boys are also in Group H and Ronaldo acknowledged that a tough task lies ahead for Juventus, who reached the quarter-finals last season.
“The Champions League is my favourite tournament,” he said.
“It’s a very difficult group, we know that we can do well and Juve must focus on being the best
