After requesting a move away from the Premier League side in the summer, it looks like the 37-year-old could finally get his wish in January, having started just one Premier League game this season.
The Florida-based club, founded by former United man David Beckham, has already attracted superstars like Gonzalo Higuain, who recently announced his retirement from football.
However, Ronaldo would be a different level entirely, especially with him still being regarded as a truly elite player - in spite of his age.
While its unclear whether the forward would be keen on a move state-side, the Mirror claims that there is clear interest from Inter Miami, who are currently coached by another former Red Devil in Phil Neville.
Nevertheless, the outlet suggests that a move would only be possible on the condition that it was a free transfer.
It's likely that Manchester United would demand a fee of some kind, with £10 million being mooted as the magic number in some reports.
Miami aren't expected to be the only side in for Ronaldo this winter, as the race to land one of the biggest stars in world sport will surely hot up as we approach the end of the year.
Any thoughts of Ronaldo re-establishing himself in Erik ten Hag's first choice XI were firmly extinguished last weekend, as he was benched for United's humbling 6-3 defeat to rivals Manchester City.
The Portugese superstar didn't play a second, in what was a clear indication of his place in the pecking order as things stand.
With business notoriously difficult to conduct during January, its hard to imagine United letting Ronaldo go on a free.
It's been a tumultuous Premier League return for him since rejoining his former club in the summer of 2021.
On the face of it, 24 goals from 39 appearances last season was a more than decent return in what was a poor campaign for all-round for United.
And yet, rumours of dressing room clashes and discontent soon started to emerge, eventually leading to Ronaldo's transfer request earlier this year.
Alongside interest from Inter Miami, Turkish giants Galatasaray have also been mentioned as an interested party.
A move there would allow Ronaldo the opportunity to play in his beloved Champions League for another season or two, where he'd have the chance to extend his record tally of goals in the European competition.
