Manchester United striker Marcus Rashford has signed a new contract that will keep him at the club until June 2020, with the option for an additional season.

The club also confirmed that defender Cameron Borthwick-Jackson has inked a new deal with the same length and extension option.

Rashford's previous deal was due to expire at the end of the 2016-17 season, but the young striker has been rewarded for his fine performances this campaign with a new and improved contract.

The 18-year-old came through the ranks of the United youth academy and made his first-team debut in the 5-1 Europa League win over Midtjylland back in February, scoring twice.

He has since gone on to score eight goals from 18 appearances in all competitions, earning a call-up for England's provisional Euro 2016 squad.

"I am delighted to have signed a new contract. I have always been a Manchester United fan, so to be playing in the first team really is a dream come true,” Rashford said. "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."

Borthwick-Jackson, meanwhile, was handed a first-team debut in United's Premier League game against West Bromwich Albion in November.

The fullback went on to make 14 appearances for the first team and also picked up the Under-21 Player of the Year award at United's end-of-season awards.

"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."

Executive vice chairman Ed Woodward was delighted with the renewal of two of the club's most promising youngsters and is confident they both have a bright future ahead of them at United.

He said: "Marcus is a naturally talented footballer with great potential. 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.

"Cameron is one of a number of young players to come through our academy to make their first-team debut last season. This is something that our club has always done and promoting the academy and U21 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."
