Stollenwerk began his international career in 1951 playing as an
inside right linkman. He proved to be a versatile player, being used in every position, including
goalkeeper. During the
1958 FIFA World Cup, Stollenwerk was chosen to replace
Fritz Herkenrath in the goal in case he got injured (with no substitutions being allowed). His main position, however, was that of an
inside forward. This changed in 1957, when
1. FC Köln coach
Hennes Weisweiler converted Stollenwerk to
right back. This proved to be a good career move for him, as he felt at home in that role immediately and played convincingly enough to be called up again for international duty by
Sepp Herberger. Previously, as an inside forward, he was only sporadically used by Herberger; however, at the
right back position Herberger was looking for a fitting successor to
Jupp Posipal, who had quit his international career in 1956. By 1958, Stollenwerk had become the standard
right back of
West Germany, allowing
Herbert Erhardt to play as
centre half instead of
full back. Stollenwerk played in every German game at the
1958 FIFA World Cup and won 23 caps in total. Stollenwerk retired from football in 1962, after winning the
German football championship with 1. FC Köln. Later on he was a trainer for
Alemannia Aachen,
TuS Langerwehe and 1. FC Köln. ==References==
