The 21-year-old has been used sparingly since arriving in Germany, making just four substitute appearances for the Bundesliga outfit, but claims to be enjoying his time at the Mercedes-Benz Arena.
Macheda is set to stay at Stuttgart for the remainder of the 2012/13 campaign, after agreeing a temporary switch away from the Premier League in the January window.
Sir Alex Ferguson had high hopes for the talented youngster, who burst onto the scene when he made his Red Devils debut. However, after a lack of progress over the past few years, Macheda is now ready to embark on a new chapter of his faltering career.
"In the winter, the move (to Stuttgart) was only a loan option but I knew there would be a chance to remain at the club after it," the Manchester United striker told German newspaper BILD. "If Stuttgart want to sign me permanently, I would be very happy.
"Back at Manchester United it was always difficult for me due to the competition for first team spots.
"It would be great to remain at Stuttgart. Over here the coaches are working with young players and I feel I could progress at this club as a player."
