Karl-Heinz Schnellinger is a German former footballer who played as a defender. An athletic and hard-tackling player, with a strong physique, he was nicknamed the "Volkswagen" for his continuity of performance, both in quantity and in quality, and for his versatility; indeed, although he was usually deployed as a full-back, he was capable of playing anywhere along the back, and could also play as a centre-back, as a sweeper, or even as a defensive midfielder. In his prime he was often considered one of the best and most complete left-backs in the world in his era, rivaled only by Giacinto Facchetti, Nilton Santos and Silvio Marzolini.

Düren is a town in North Rhine-Westphalia, Germany, between Aachen and Cologne, on the river Rur.
