Case maintained his place the following year (1976–77) as Liverpool chased a unique treble of League Championship, FA Cup and European Cup. They were league champions for the second season in a row, but lost in the 1977 FA Cup Final to Manchester United 2–1. Case was the scorer of Liverpool's goal shortly after their opponents had taken the lead; it was a typical Case goal, a thundering shot from outside the penalty area following a neat turn on the ball. He was in the team again a few days later when Liverpool won the 1977 European Cup Final, beating Borussia Mönchengladbach 3–1 in Rome.
