Marcus Rashford has signed a new contract which will keep him at Manchester United until at least 2020 while Cameron Borthwick-Jackson has also committed to a similar deal.
Rashford’s new agreement also includes an option to extend for a further year.
“I am delighted to have signed a new contract,” the England international told manutd.com.
“I have always been a Manchester United fan so to be playing in the first team really is a dream come true. I am grateful for having the chance to prove myself.
“To be able to play football at the biggest club in the world means everything to me and my family.”
Rashford burst onto the first-team scene in February, scoring twice on his debut in the Europa League against Midtjylland.
The teenager repeated the feat three days later on his first Premier League appearance against Arsenal and went on to score eight goals in 18 appearances.
Rashford also scored within three minutes of his senior England debut in a friendly against Australia on Friday to enhance his chances of going to Euro 2016.
United executive vice-chairman Ed Woodward praised the youngster and the progress he has made.
“Marcus is a naturally talented footballer with great potential,” he said.
“He has taken his chances well and has integrated into the first team very quickly.
“I am delighted that Marcus has signed a new contract. He is at the right club to continue his development.
“He is still very young and we need to be patient but he is developing in the right way and we believe he has a great future ahead of him.”
Borthwick-Jackson, who also came through the academy ranks to make his first-team debut against West Brom in November, made 14 appearances and was named United’s under-21 player of the year.
“I have grown up at United and have enjoyed every minute of being here,” said the 19-year-old.
“Last season was an incredible experience to make my first-team debut and a dream come true for myself and my family.
“I feel it stands me in good stead for continuing my development as a Manchester United player.
“I will continue to work hard and take advice from the manager and his coaching team to improve with every training session.”
Woodward added that the progress of the club’s youngsters was an immense source of pride.
“Cameron is one of a number of young players to come through our academy to make their first-team debut last season,” he said.
“This is something that our club has always done and promoting the academy and under-21 players is something that makes everybody associated with the club very proud.
“I’m delighted that Cameron has signed his new contract and look forward to seeing him in the squad for many years to come.”
