The Italian began his career with Lazio’s youth team before moving to England, and is currently on a season-long loan at United's English Premier League rivals Queens Park Rangers.
But he has found first-team opportunities limited at both Old Trafford and Loftus Road, and he is now planning on a return to Italy with his boyhood club Lazio.
"I'd like to come back to Lazio in the future, I always said it, but I don't know my future yet," he told Corriere Dello Sport
"I have a contract with Manchester United until 2014, but in June I will end the loan and we will see."
The one-time Sampdoria loanee went to see Lazio in the Rome Derby on Sunday after QPR boss Mark Hughes gave the squad a day-off.
And the 20-year-old watched the Biancocelesti beat Roma 2-1 with the Lazio fans in the Curva Nord of the Stadio Olimpico.
"Last Wednesday the QPR coach said to us that we had a day free on Sunday, without training," Macheda said.
“So I decided to come to Italy to see Roma [against] Lazio. I visited on a day trip as I left London in the morning and I came back in the evening.
“I wanted to see the 'derby' in Curva Nord, to stay with the Lazio fans. It was a strong emotion. I was there with my friends and my cousin.”
Lazio’s win saw them climb above Udinese into the third and final Champions league place, but former player Djibril Cisse was not there to see them beat city rivals Roma, after Macheda revealed that the Frenchman turned down the opportunity to travel to Italy to watch the game.
"I asked Cisse if he wanted to come with me but Djib had other plans, he couldn't come with me," Macheda said.
“He saw the match on TV, and he was happy for Lazio’s victory. We talked about it yesterday too before training."
Macheda joined United in 2007 as a youth player, and scored one of the most important goals of the season for the club in 2009 as they came from behind to beat Aston Villa 3-2 on the way to winning the Premier League title.
