Speaking to JuventusTV, as quoted by Goal, Ronaldo outlined why he chose Juve above anybody else.
Thousands of fans flocked to get a glimpse of Ronaldo at the small town of Villar Perosa outside of Turin, where the Juventus owners hold a pre-season friendly between the first team and the reserves every year.
Controlling a long pass from Federico Bernardeschi, Ronaldo calmly looked around him to make sure he had time to take a touch, before slamming the ball into the top corner.
He played a part in the second goal as well, putting Riccardo Capellini under pressure as a low cross came into the box and the Juve youngster put past his own goalkeeper.
The gesture was duly appreciated by the five-time Ballon d'Or victor, who held his hands up and graciously stuck his thumbs up. One said "Welcome Ronaldo" and another had his face on it and simply read CR7, in reference to the jersey number Ronaldo made famous as a Real Madrid player.
And Ronaldo certainly showed no signs of rustiness after his break as he opened the scoring for the first team just eight minutes into the game.
After representing his country at the World Cup in Russian Federation this summer, the 33-year-old was given extra time off to recover properly for the new season.
The friendly, which takes place annually, represented Juventus' final test before they kick-off their Serie A title defence against Chievo next Saturday.
Ronaldo stunned Real Madrid fans last month when he joined Juventus for an Italian league record sum of €112 million (NZ$194m). Juventus has lost five finals since its last European Cup success.
