With Bayern he won the European Cup in 1975 and 1976. In 1975, he did not take part in the final of the competition, whilst in the year thereafter a glass of brandy sufficiently prepared the nervous Rummenigge to contribute to the defeat of AS Saint-Étienne. In the same year he became also part of the team that prevailed in the Intercontinental Cup finals against Cruzeiro EC from Belo Horizonte.
