I wouldn't say Ronaldo is currently unhappy. He was for a while, Madrid supporters booed him on more than a few occasions. Last year of Mourinho was a disaster for pretty much all Madrid players. Right now though everything is going great for him. He is appreciated and is doing very well. I really doubt he'd give up all the success he has in Madrid to go to United who are in sort of a slump. Maybe a few years down the line.
