Manchester United F.C. Reserves and Academy

Manchester United Football Club Under-21s is the most senior of Manchester United's youth teams and the club's former reserve team. They play in the Premier League 2, the highest tier of the Professional Development League. The team is effectively Manchester United's second-string side, but is limited to five outfield players and one goalkeeper over the age of 21 per game following the introduction of new regulations from the 2022–23 season, a change from three outfield players over age 23 introduced in 2016–17. The age limit previously was again 21, from 2012–13. The team's current manager is Adam Lawrence, who took over from Travis Binnion in 2026.
