On 3 March 1976, on Ash Wednesday, was the next sensational international appearance of Borussia. In the European Champions Cup, Borussia Mönchengladbach played against Real Madrid, where now Günter Netzer and Paul Breitner were under contract, 2: 2. In the second leg (17 March 1976), which ended 1–1, the referee Leonardus van der Kroft did not recognise two Mönchengladbach goals, in the 68th minute a goal by Henning Jensen and in the 83rd minute by Hans-Jürgen Wittkamp. Once a foul must have preceded the goal, once the referee decided on offside, although it had been not indicated by the linesman. The draw was enough for the Madrilenians to progress.
