Michael Zorc has signed a one-year contract extension to remain as Borussia Dortmund's sporting director until 2022.
Zorc has been at Dortmund since 1978 and assumed his current post in 1998.
Dortmund have won three Bundesliga titles, two DFB-Pokals and reached the final of the UEFA Cup and Champions League in that period.
"A few weeks ago, I made a personal request to Michael Zorc to stay with us for an extra year," said CEO Hans-Joachim Watzke.
"We at BVB are all happy and thankful that he has complied with our request. Michael is a true 'Borusse' and, as such, he was prepared to continue overseeing sporting matters at a time that is challenging for us all, and during which it is difficult to plan and tough to predict developments.
"This continuity will do us good."
Zorc added: "We're facing a period that will present significant challenges.
"It goes without saying that, during such a phase, I will stand by my club and make my contribution as we strive to put Borussia Dortmund on the best-possible footing together."
Dortmund round off a campaign that was halted in March by the coronavirus pandemic when they host Hoffenheim on Saturday. They are guaranteed of a second-placed finish behind champions Bayern Munich.
Their failure to keep pace with Bayern, along with their elimination from the Champions League at the hands of Paris Saint-Germain, has seen coach Lucien Favre come under scrutiny
