Midfielder Kobbie Mainoo has signed a new five-year contract with Manchester United, keeping him at the club until 2031.
The agreement replaces his previous deal, which had been set to run until the summer of 2027, and reflects his rapid development and growing importance within the first team.
Mainoo’s earlier contract at Old Trafford was agreed in 2023 when he was just 17 years old.
The updated terms underline his rise through the ranks and his current standing in the squad.
Uncertainty had previously surrounded his long-term future during the tenure of Ruben Amorim, where he was limited to a single start this season in the Carabao Cup before the manager’s dismissal in January.
However, under Michael Carrick, the academy graduate has re-established himself as a key figure in midfield. His strong performances have also earned him a recall to the England national team setup.
United’s director of football Jason Wilcox praised the youngster, describing him as “one of the most naturally gifted young footballers in the world”.
Wilcox added: “We are delighted that Kobbie has extended his stay here and have full confidence that he will develop into one of the best players in the world, ready to play a pivotal role in a Manchester United team challenging for the biggest honours.”
Despite being only 21, Mainoo has already produced standout moments for the club, notably scoring the decisive goal in the FA Cup final at Wembley, securing a 2-1 victory over Manchester City in 2024.
His senior debut came under Erik ten Hag in a Carabao Cup fixture in January 2023, following his influential role in United’s FA Youth Cup triumph the previous season.
Speaking to the club’s official website, Mainoo said: “Manchester United has always been my home – this special club means everything to my family.
“I have grown up seeing the impact that our club has on our city, and I relish the responsibility that comes with wearing this shirt.
“From The Cliff, to Littleton Road, to Carrington and ultimately Old Trafford, the journey so far has been incredible.
“I have the privilege of living my dream every single day, with the same relentless desire to succeed here as when I joined my first training session at the age of six.
“We can all feel the momentum building inside the club. I am determined to step up and play my role in helping Manchester United to regularly fight for major trophies in the years ahead.”
