Answer
Feyenoord was the first club managed by Ernst Happel. The Austrian coach began his managerial career with the Dutch club in 1962, leading them to two Eredivisie titles and a European Cup victory in 1970. Happel's success at Feyenoord established his reputation as one of Europe's top managers, and he went on to manage several other major clubs, including Hamburg, Bayern Munich, and the Austrian national team.
