He won the illustrious UEFA Champions League trophy with Manchester United and with Real Madrid.
According to Madrid-based paper Marca, the club have a superstar-filled list of alternatives to fill the Portuguese's sizable boots - chief among those being Tottenham's Harry Kane. "I'm leaving but this shirt, this crest and the Santiago Bernabeu will continue to always feel as my own wherever I am". "Apart from the titles he has lifted, the honours secured and the on-field achievements during these nine years, Cristiano Ronaldo has been a role model in terms of commitment, hard work, responsibility, talent and self-improvement". Paolo Rossi, Michel Platini, Zinedine Zidane, Pavel Nedved, Roberto Baggio, Alessandro del Piero and Gianluigi Buffon all have their images plastered on the walls of Juve's Allianz Stadium, and you can bet that Ronaldo will do something to earn his place alongside them. The Italian club said: "He's called Cristiano Ronaldo and he's now officially a Bianconero!"
The 33-year-old striker is expected to have a medical in Turin next week before being unveiled by his new side.
However, as the Spanish giants prepare for life under new head coach Julen Lopetegui, Ronaldo felt the time was right to move on.
"Ronaldo leaves Madrid as the club's all-time leading scorer, with 450 goals in 438 games".
And it is that kind of ambition that will keep the Belgian in London, who wants to win the Champions League.
Juventus is a storied club with iconic former players and Ronaldo will relish the opportunity to add his name to their roll of honour. Juventus showed him respect when he was an opponent; just imagine how much he will be indulged as one of their own.
Football finance expert Rob Wilson of Sheffield Hallam University agrees.
Madrid have released statements lately denying media reports that deals had been agreed for Mbappe and Neymar. "My respect and gratitude goes out to them all".
So, Ronaldo has signed up for a challenge as well as a change of scenery.
