The club had to wait several decades before their first realistic chance at cup silverware, when they began the first of a six-game losing streak of Scottish Cup Final appearances in 1974, losing 3–0 to Celtic. Towards the end of the 1970s, things began to change, with three successive appearances in the League Cup Final. United won their first major trophy with a 3–0 replay victory over Aberdeen in the 1979–80 Scottish League Cup Final. The club reached both cup finals in the following season; while they retained the League Cup by winning 3–0 against rivals Dundee, United lost out again in the Scottish Cup with a replay defeat to Rangers. United reached a third consecutive League Cup Final in 1981–82, but failed to make it a hat-trick of wins as they lost 2–1 to Rangers.
