Bert van Marwijk was appointed Borussia Dortmund coach, replacing Matthias Sammer who was fired at the weekend.
The 1997 European champions said the 52-year-old Dutchman had signed a two-year contract.
Sammer, who was fired by Dortmund on Sunday, was named Stuttgart coach 24 hours later. He replaces Felix Magath, who has moved on to Bayern Munich.
Ruud Gullit will take over from Van Marwijk at Feyenoord.
