The 2014–15 season began well. The highlight event of the season's first month was being drawn against Manchester United in the League Cup second round, having dispatched AFC Wimbledon in the first. The Dons recorded a shock 4–0 victory over Manchester United in front of a sell out crowd at Stadium MK. A few weeks later, the Dons recorded their record win, a 6–0 thrashing of Colchester United at home. That record did not last long as it was broken once again with a 7–0 demolition of Oldham Athletic on 20 December 2014. Just over a month later, on 31 January 2015, the Dons recorded a joint record 5–0 away win against Crewe Alexandra, earning a short-lived top spot. On 3 May the club secured promotion to the Football League Championship for the first time, beating Yeovil Town 5–1 and leapfrogging Preston North End (who lost 1–0 at Colchester United) on the final day of the season.
