The season is best remembered due to the club's journey around the European Cup defeating Irish side Limerick in First Round, in Eightfinals won 3–0 against Budapest Honved, advancing 2–0 against Soviet side Spartak Moscow in Quarterfinals and won the series 2–1 in semi-finals against Italian Champion F.C. Internazionale Milano reaching its first Final of the tournament after 15 years. Before the final, President Luis de Carlos reached an agreement with a German supplier being the first time ever the club play with a branded shirt openly. However, with Stielike and Cunningham having physical issues the squad lost 0–1 the Final against then-heavily favourites English side Liverpool F.C. recent back-to-back champions in 1977 and 1978.
