Ronaldo, 34, has continued to star after joining the Old Lady last year, scoring 28 goals in 43 games in all competitions and helping the Italian giant win another Serie A title in 2018-19, goal.com reported.
The five-time Ballon d'Or winner is uncertain when he will stop playing, although he intimated that it may not be far away.
"I don't think about that," Ronaldo told TVI.
"Maybe I can finish my career next year... but I can also play up to 40 or 41.
"I don't know. What I always say is to enjoy the moment. The gift is excellent and I have to continue to enjoy it."
Along with numerous individual honors, Ronaldo has won a record five Champions League titles (four with Real Madrid and one with Manchester United), three Premier League crowns, two La Liga trophies, and one Serie A title.
Ronaldo wants to make history and is seemingly motivated by setting records.
"Are there any football players who have more records than me?" he asked.
"I don't think there are any footballers who have more records than me."
His teammate Sami Khedira likened the ex-Manchester United attacker's standing in football to the role of superstars in other sports – and as having the work ethic of legendary Italian goalkeeper Gianluigi Buffon.
"Ronaldo is an example for all sportsmen, like LeBron James in basketball or Tom Brady in American football," Khedira told Kicker.
"Or like [Gianluigi] Buffon. When the boys see Gigi pushing weights for 45 minutes, at 41, they understand his love for this sport and can only think, ‘I can do it too.’
"Older players are a great motivator for the younger ones."
With Serie A having a later start to the season than Europe's other strong leagues, Juventus begins its campaign to win a ninth straight Scudetto away to Parma on Saturday.
Juve faces a tough opening to the season, with fixtures against Fiorentina (away) and Napoli (home) to follow after its opening weekend match.
