Juventus broke their own transfer record to bring Ronaldo to Turin, eclipsing the £75.3 million they paid for Gonzalo Higuain.
Real Madrid are undergoing a structural change of sorts with a new manager in place and their star player now gone. There are also rumours linking the Spanish club with Paris St-Germain's Brazil forward Neymar who transferred to the French capital just last year in the highest-ever £198 million transfer deal.
Ronaldo wrote an open letter about his transfer, saying his time in Madrid had been "possibly the happiest of my life". The reigning Ballon d'Or winner also thanked the fans, staff, coaches, and fellow players.
"Real Madrid has conquered my heart, and that of my family, and that is why more than ever I want to say thank you: thank you to the club, the president, the directors, my colleagues, all the staff, doctors, physios and incredible people that make everything work," the player said.
Ronaldo said he requested Real Madrid for the transfer, believing that "the time has come to open a new stage in my life", and asked followers to "understand" his decision.
Real Madrid also released a statement saying that they had agreed to Ronaldo's transfer request.
"Real Madrid would like to express its gratitude to a player who has proved to be the best in the world and who has made this one of the most brilliant times in the history of our club," the statement said.
