On 28 January 2012, Agger opened the scoring against Manchester United in the fourth round FA Cup tie, defeating them 2–1. It was his first Liverpool goal since 2010, when he scored in the Europa League tie against Benfica. On 26 February 2012, he helped Liverpool to win their first trophy since 2006 as they won the 2012 Football League Cup Final but injured his ribs during the match. On 7 April 2012, Agger made his return from injury as a second-half substitute against Aston Villa at Anfield, replacing José Enrique and hitting the crossbar with a header late on which led to the equalizer in a 1–1 draw. On 8 May 2012, Agger scored his first Premier League goal of the season in a 4–1 win against Chelsea which was also the last home game of the season for Liverpool.
