Juve's title was confirmed with victory over Fiorentina.
Ronaldo spoke to DAZN first and was asked about reports he could walk away from the Old Lady.
“I am staying at Juve, 1,000 per cent," he replied.
“In my opinion, it was a very good first season and I adapted well. We won the Scudetto and the Italian Super Cup, which is certainly not easy to achieve.
“After winning the league in England and Spain, now I can say I've won it in Italy too. It was important to me and I'm very happy."
Ronaldo continued: “It was a year of success, we are happy. You can't win all the time. We felt that we could do more and we wanted to win, but only one side can win the Champions League.
“Next year is a new page, the fans all want it and so do we. It is an important trophy, but it's difficult to get there in this tournament. It's a positive group and I believe it has been a good season."
