This initial outrage on behalf of FC Köln supporters was soon met with a serious sporting rivalry: Although Cologne initially had had the athletic edge as a founding member of the Bundesliga and the league's first champion, Mönchengladbach quickly closed the gap. Between the seasons 1969–70 and 1977–78, Mönchengladbach won five championships, Cologne won one, and FC Bayern Munich secured the remaining three. The 77–78 season has become remembered in both club's collective memories: Although Mönchengladbach defeated Borussia Dortmund in the highest victory in Bundesliga history with a crushing 12–0, Cologne carried the championship with a 5–0 win over FC St. Pauli due to their slightly better goal difference (+45 versus +42 in Cologne's favour). To add insult to injury, Cologne was back under the leadership of Hennes Weisweiler, the personified point of contention between both clubs.
