Chris Eagles left Old Trafford over the summer and dropped down into the Championship with Burnley.
However, the 23 year old has admitted that he would welcome the opportunity to rejoin Manchester United in the future.
"I'm not going to hold a grudge because I thank him (Ferguson) for everything he's done. He's got me to where I am today and I have learned so much from him," Eagles said in the Daily Star Sunday.
"You have got to have a basic talent but he adds to it. He didn't want me to go. It was sort of on my own back and he fully understood.
"But he's got a clause now that he can buy me back first. I got on so well with the gaffer. He's like a second father to me.
"We had our ups and downs and he used to tell me off if I was in trouble. But I wouldn't change it.
"It was a very hard decision to go because I had a few Premier League clubs interested as well.
"But I felt I wanted to make my own name and be my own person. The manager knew that and I know he watches me every week to keep an eye on me.
"You never know. My dream is that one day I will go back. My dream is to play for England, too, and I'm going to stop until I get that."
