"You don't win five Ballon d'Or trophies for nothing and you can see how hard he works to get there".
Not since 1995/96 have Juve won Europe's elite competition but with Ronaldo now in their ranks they've never had a better chance of ending that drought.
"This year, our ambition to win the Champions League is greater than in previous years, as is the desire to win the league, Coppa Italia and Supercoppa, but nobody is going to gift us anything before we've won them", he told Sky Sport Italia.
"Ronaldo has above all brought experience at worldwide level and is an extra motivation for the younger guys to aim higher".
"I am used to following Juve and I like the club, but since that moment I liked them even more".
Brazilian Ronaldo in intensive care with pneumonia
According to the Diario de Ibiza , he has now been admitted to the ICU of the Nuestra Señora del Rosario Polyclinic . He scored 62 goals in 98 games for Brazil , as well as being a prolific scorer for some of Europe's elite clubs.
He was at both the 2017 Champions League final in Cardiff, when Ronaldo scored a brace as Real Madrid hammered Juve 4-1, and in Madrid last season when the Portuguese slotted the last-gasp penalty that knocked Juve out in the quarter finals.
As well as Ronaldo, new signings Emre Can and the returning Leonardo Bonucci were present at Juventus Stadium for the warm-up match. "Ronaldo will repay Juve not just in goals and results, but also in economic terms".
Old Lady fans gathered in decent numbers to see the five-time Ballon d'Or victor at Villar Perosa - in a rural area of Piedmont in northern Italy and cheered him on as Ronaldo showed his full array of tricks and impressed on his Juve debut.
The fan was swiftly dealt with by stewards and was escorted off the pitch.
"What matters most now are matters on the pitch", said Juventus manager Massimiliano Allegri after the game - which the club described as a "Bianconeri party".
