Ronaldo, who signed for Juventus from European champions Real Madrid in a shock 100 million euro ($117 million, Sh11.7 billion) deal exactly a month ago, will wear the Juventus kit for the first time in the club's traditional pre-season friendly between Juve's first XI and a "B" team in Villar Perosa, a small town 40 kilometres (25 miles) west of Turin.
Ronaldo, who joined the Serie A champions last month in a deal worth a £100million, made the ideal start to life in Turin.
Ronaldo told the BBC that he was "grateful for the opportunity" to transfer to Juventus at this stage in his career, as players of his age usually "go to Qatar or China", apparently. It was wonderful. Something like this had never happened to me. In the Champions League against Juve, a quarter-final, you score a goal and see everyone in the stadium applaud you.
"I felt surprised at first". Since I was a kid, I looked at this team and said I hope to play there one day.
"It's a great club, first of all", Ronaldo said in the interview.
"I won't say it was the key point in my decision, but every detail helps".
He reiterated those comments in the interview with the club, saying that while he could not recall a precise reason he chose to join Juve, that one was among several that helped him make the decision.
"We've met Juventus on a couple of occasions in recent years and I've always had the feeling that Italian fans liked Cristiano".
ESPN have snatched the rights to broadcast Serie A in the United States from BeIN Sports (although the league has not said how much the network will pay) and World Cup Golden Ball victor Luka Modric is also pondering a move to join former teammate Ronaldo in Italy - at Juve's arch rivals Inter Milan. "That's my job. I'll try to enjoy it as much as I can and make Juventus even better".
