On 10 May 2010, Karl Robinson was appointed as the club's new manager, with former England coach John Gorman as his assistant. At 29 years of age, Robinson was at the time of his appointment the youngest manager in the Football League. In his first season in the club Milton Keynes Dons finished fifth in 2010–11 League One. They faced Peterborough United in the play-off semifinals. Although they won the first leg 2–1, a 2–0 defeat at London Road meant they missed out on the play-off final, losing the Semi-Final 3-2 on aggregate goals.
