The club's coach, Massimiliano Allegri, has said that in the midst of media speculation, the town of Manchester might be his next destination.
This weekend, Allegri told a news conference in advance of his side's Series A clash with Empoli that 36-year-old Ronaldo had informed him of his willingness to leave Turin on Thursday.
“Yesterday Cristiano told me that he no longer plans to play for Juventus,” Allegri said. “This is why he will not be called up tomorrow. He did not train yesterday. He told his team mates this morning. I am not surprised at anything, in football there is the market and there are the needs of individuals.
“He made his choice. Life goes on.
“Omar Sivori, Michel Platini, Alessandro Del Piero, Zinedine Zidane, Gianluigi Buffon, some great champions and even better managers (have left). It’s one of the laws of life. But Juventus will always be here.
“Cristiano did a lot for this club, he’s a great champion, I wish him all the luck in the world wherever he will play. He gave a great contribution. For the season that I trained him he led by example for the lads, so he is only to be thanked for what he did for Juventus.”
In order to lead them to an elusive title in the Champions League, Ronaldo, signed in 2018 by Juventus for 100 million euros by Real Madrid will leave the Italian club with its 101 goals, two titles in the league and the Copper Italia Trophy on its name.
Ronaldo spent six seasons with Manchester United from 2003 - 2009 winning eight major trophies, as well as the Ballon d'Or as the best player in the world, in 2008.
Ronaldo joined Iran's Ali Daei as the all-time top scorer in international soccer during the European Championships in June by reaching 109 goals, and he could make his own record during the World Cup qualifications in September.
Ronaldo will join a talented City team without a consistent leader after the all-time lead scorer, Sergio Aguero, leaves to Barcelona at the end of the 2020-21 season.
English champions City failed this week to sign a signature by Harry Kane from Tottenham Hotspur, who stayed in the north club of London with the captain from England.
At United, Ronaldo scored 118 goals and won the Golden Boot Premier League in the 2007-2008 season in the Old Trafford club's last championship title.
