The five-time winner of the Golden Ball joined the perennial champions of Serie A after his relationship with Real Madrid broke.
And Ronaldo has lost little time identifying players he thinks will help in his Champions League campaign.
Milinkovic-Savic was linked with Manchester United and Chelsea during the summer, but the transfer window of the Premier League is now closed.
Juventus and the rest of Europe, however, still have until August 31 to strengthen their squadrons.
And Ronaldo wants the Old Lady to recruit the Serbian midfielder to galvanize the engine room of his new club.
Don Balon, known for his extravagant transfer rumors, claim that Ronaldo has assigned Milinkovic-Savic as a future Juve star.
The 23-year-old represented his country in the World Cup this summer, but Lazio will not let him play cheaply.
According to the report, the former Genk star has a price tag of £ 98.4m in her head.
Milinkovic-Savic bagged 14 goals and eight assists for Lazio to help them secure a fifth place in Serie A last season.
"Now I will play for a fantastic club"
Ronaldo could make his debut at Juventus against Chievo on Saturday (5pm), and yesterday he talked about what motivated him to play for the Turin team.
He told JuventusTV after connecting with his new teammates for pre-season training: "Great club, first of all it's a great club
"Since I was a child, I looked at this team and said I hope to play there someday.
"Now I will play for a fantastic club, one of the biggest in the world, I'm happy, I do not have a precise moment when I decided.
"Over the years, we played a few times against Juve and I had the special feeling that Italian fans like Cristiano.
"It's the biggest club in Italy, one of the best in the world, so it was an easy decision, since Juve is an incredible club."
