Juventus are claimed to be keen to cash-in before his contract expires in 2022 and offload his sky-high £850,000-a-week wages.
But Madrid-based outlet AS have claimed Ronaldo has no intention of leaving next year.
The Spanish paper have suggested the former Real Madrid star will wait until he's a free agent in 2022 to move on.
The report also stated Juventus are happy to keep hold of their star man until the end of his current deal - unless they don't win the Champions League.
However, Man Utd could decide they don't want to wait until Ronaldo is 37 for his eagerly-anticipated homecoming.
Portuguese outlet Record have claimed United officials have already been in touch with Ronaldo's agent to make their interest formal.
And Ronaldo could be tempted to cut short his spell in Turin, too - thanks to Lionel Messi.
