MLS appears to be the most likely destination for the Portugal international if his contract with United expires at Old Trafford in the summer of 2018.
A enticing offer from Inter Miami has been put in front of Cristiano Ronaldo, according to Todo Fichajes, and the Portuguese international has suggested that he will take it and join David Beckham's club in the summer.
In spite of the fact that he turned 37 last month, Cristiano Ronaldo still appears to have a lot to contribute at the highest level, albeit perhaps not on a consistent basis.
However, it is possible that the veteran forward has reached the point in his career when he is ready to play at a somewhat lower level of competition and will seek to finish his career in the Major League Soccer.
Ronaldo's second stint at Manchester United may leave the club's fans unhappy, but it might also be an opportunity to move on and create something fresh without him.
Manchester United have a number of young players at the peak of their game who have the potential to make a significant contribution at Old Trafford, and it may be easier for the club to go all out to sign a big name if they can remove Ronaldo's deal off their payroll.
