“I’d like him to come to Italy one day. I hope he accepts the challenge like me, but if he’s happy there then I respect that,” Ronaldo told the Italian press on Monday.
The two strikers have been rivals for the past decade winning five Ballon d’Or trophies each before their domination was broken by World Cup runner-up Luka Modric last week.
Asked if he missed the 31-year-old Argentinian, who has spent his entire senior career at Barcelona, Ronaldo replied: “No, maybe it’s him who misses me …
“I’ve played in England, Spain, Italy, Portugal and for my national team, while he’s still in Spain.
“Maybe he needs me more… For me, life is a challenge, I like it and I like to make people happy.
“He’s a fantastic player and a good guy, but I don’t miss anything here. This is my new life and I’m happy.
“I left my comfort zone and took on this challenge here in Turin, everything has gone well, I’ve proven I’m still an incredible player,” said Ronaldo.
Ronaldo joined Juventus for €100m ($114m) last summer as the Turin giants bid to lift the Champions League trophy after two runners-up finishes in the past four seasons.
To mark his 150 days in Italy he gave interviews on Monday to three leading sports dailies: La Gazzettadello Sport, Corrieredello Sport and Tuttosport.
“I had different options. I won’t say which but I had them. Juventus is a solid club. It has a long history,” he said of his decision.
“I knew the atmosphere in the stadium. I’d played several times in Italy. I like the city, the people and the club. I knew it could work.
“I couldn’t be 100 percent sure I was joining the best club in the world. After nine years at Real Madrid it was difficult to compare.
“Now I’m 100 percent sure it was the right option.”
Ronaldo has scored 11 goals this season, bringing his career total to 584. Finishing second in Ballon d’Or voting to Modric, said Ronaldo, just motivates him even more.
