Manchester United striker Federico Macheda has signed a four-year contract extension to stay with the Premier League champions until 2014.
Macheda announced himself as a potential star of the future last season when making a stunning impact on his United debut.
The Italian teenager was introduced as a substitute against Aston Villa in April and scored a dramatic injury-time winner which played a key role in United going on to secure a hat-trick of top-flight titles.
He followed that up with another decisive contribution against Sunderland just a week later and he also started the FA Cup semi-final against Everton.
This season, the 18-year-old has made five appearances for United, although he has yet to feature in the Premier League.
Macheda was a second-half replacement for Dimitar Berbatov in Tuesday's Carling Cup quarter-final against Tottenham Hotspur, having started against Wolves and Barnsley in previous rounds.
He has yet to score this season, but is likely to be given another chance to impress in next week's final UEFA Champions League group game against Wolfsburg.
The emergence of Macheda, who was recently linked with a loan move to Middlesbrough, was highlighted as a key reason why Sir Alex Ferguson did not spend big over the summer.
Ferguson has now rewarded Macheda with a new long-term deal as he looks to secure the futures of the club's most promising youngsters.
The United boss told the club's official website: "We are delighted by the new four-year deal, everyone at the club recognises the fantastic talent he has and we hope to see that develop in the next years, so he becomes a well rounded player."
Macheda added: "I am very happy to commit my future to Manchester United.
"I really enjoyed myself last season when I came on and I hope to get more chances like that and contribute to the team's success."
