Juventus hope Ronaldo will leave them to Champions League glory after he won it three times in a row with Real Madrid and and four times in total.
“This season we have the ambition to win the Champions League,” Massimiliano Allegri said last Sunday.
“After two finals lost [over the past four years] we are trying to finally bring it home.”
The five-time Ballon d’Or winner, 33, is the man with the record to do it.

Ronaldo’s arrival has already seen one casualty with Gonzalo Higuain pushed out to AC Milan.
And Paulo Dybala and Mario Mandzukic’s places are under threat.
But Allegri thinks Ronaldo is capable of playing alongside his fellow attackers.

Allegri said: “I will need to see what happens in the next 2-3 games.
“We can play with many tactical systems. Ronaldo can play with Dybala or Mandzukic, his positioning depends on his striking partner but also on who plays in midfield.
“We need to think game by game, I can use many tactical systems.
“The only thing that I must always do is to play players in their natural position.”
