Ronaldo has declared in the Portuguese press today that he is staying at Old Trafford.
Key to that dramatic development was a meeting between the player and Ferguson in Portugal just after his country's exit at Euro 2008.
"We cleared the air in Portugal, and the boy spoke to a few of the players as well," said the Scot.
"The thing is, he knows he is happy here - and has always been happy here.
"The fans have to understand it has been a very difficult time for him. He has been offered all this money - when his dad has died a young man and he is looking after his mother, his sister and his brother.
"He has had a troubled time, and you can understand that.
"But once he knew my stance, he settled down - and as far as we are all concerned, the matter is finished. The boy is a United player - that is what is important."
