Tom Cleverley has signed a new four-year deal keeping him at Old Trafford until 2015.
The 22-year-old midfielder, who has been out with an ankle injury for the last three weeks, has been eyed as a long-term replacement for Paul Scholes following his retirement from United at the end of last season.
"Tom is one of the brightest prospects in the English game," said manager Sir Alex Ferguson today. "For a young boy, he has a good footballing brain which, when coupled with his energy and ability, makes for a player with a fine future ahead of him.
"It's the United way to encourage our young players to make their mark in the first team and Tom has grabbed that chance with both hands."
Cleverley added: "It's been a fantastic start to the season for me, breaking into the first team and getting an England call-up. Having grown up at the club, I'd love to be able to make a contribution to United winning more trophies. We have a squad with great ability and I can't wait to get started again."
The youngster is expected to return for United's trip to Anfield this Saturday.
