We start our countdown with an FA Cup win at Anfield and strike duo Ian St John and Roger Hunt in top form.
After a third-round goalless draw at Vicarage Road, a crowd of 55,451 gathered at Anfield for the replay.
Two goals in just four first-half minutes from St John and Hunt put the Reds in firm control before Chris Lawler added a third.
Watford netted a late consolation but the Reds were through.
Bill Shankly's men ultimately made it to the fifth-round stage but would suffer a 1-0 defeat across Stanley Park to neighbours Everton.
