Borussia Dortmund sporting director Michael Zorc has signed a new contract that keeps him at the Westfalenstadion until 2021.
Zorc, 55, is his 40th year at Dortmund, having become sporting director in 1998 after playing 557 competitive matches from 1981.
The former Germany midfielder was a key figure as BVB came back from near-bankruptcy in 2005 to reach the 2013 Champions League final.
Referring to a difficult few months for the club that included the bomb attack on the team bus last April, Zorc told the club's official website: "I think our task now is to steer Dortmund into calmer waters."
He said he wanted to "make the team fit for the future at a high level and develop the club into a constant member of the Champions League."
CEO Hans-Joachim Watzke praised Zorc's achievements as the new contract was announced, saying: "Our success story over the past 10 years is closely connected to the name Michael Zorc.
"He stands for competence, loyalty and identification. I am looking forward to continuing our partnership."
