Mainoo signs new Man Utd deal until 2031
England international Mainoo, 21, had agreed his previous deal shortly before breaking into the first team in 2023 and it was due to expire in 2027, though there was an option to extend it by a further year. The Stockport-born academy product was marginalised under former United boss Ruben Amorim, which prompted him to push for a loan move to Italian side Napoli during the January transfer window. But United rejected that request, making clear to Mainoo that the club valued him and wanted him to stay and fight for his place.
Since Amorim's departure in January, Mainoo has has started all but one of the 12 league matches under interim boss Michael Carrick - missing a 2-1 defeat by Leeds United through injury. " Manchester United has always been my home; this special club means everything to my family," he said. "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. " As well as increased involvement in the United team since Carrick's appointment, Mainoo has also regained his place in the England set-up - featuring in friendlies against Uruguay and Japan last month.
It was the first time since Thomas Tuchel's appointment that Mainoo had earned an international call-up, and his first appearance in an England shirt since September 2024. "Kobbie is one of the most naturally gifted young footballers in the world," said United director of football Jason Wilcox. "His technical ability, dedicated professionalism and humble personality make him the perfect role model for our young players and a true credit to our outstanding Academy system.
"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. " All but back in Champions League - yet big decisions loom at Man Utd Mainoo (left) made his senior United debut against Charlton on 10 January 2023 It is still hard to get your head around the reality that had Mainoo been granted his wish, he would be playing for Napoli now - or that if United had not changed their manager in January, he would have been pushing for an alternative loan move. One of the most bizarre aspects of Amorim's tenure was that it robbed United of not only a homegrown player but one of a limited number capable of being part of a team that could deliver enough positive results to get them into the Champions League.
