In May 2014, it will be 10 years since United last lifted the famous trophy, having beaten Millwall 3-0 in the final at Cardiff's Millennium Stadium in 2004. The Reds are the record holders with 11 triumphs in the competition dating back to 1909, when United beat Bristol City 1-0 in the final.
United have a rich history in the tournament; 1948's success was Matt Busby's first trophy as manager, while in 1963 it was the first silverware won after the Munich air disaster. It was the source of success twice each in the 1970s and 1980s, while mirroring Busby's first win, Alex Ferguson made it his maiden trophy as boss in 1990.
The cup also played a part in the Doubles of 1994 and 1996 and, of course, formed part of 1999's incredible Treble, and the last success, in 2004, came courtesy of two Ruud van Nistelrooy goals and a strike from Cristiano Ronaldo.
