He has dedicated his entire life to Borussia Dortmund. He spent his career playing for this club. As a player, he won two Bundesliga titles and one Champions League title. At the age of 36, Zorc decided to retire from playing football. After retirement, he stepped up to take the position of sporting director in this club. He is still at the club and his current contract expires in 2021.With him at this position, Borussia Dortmund have had some golden moments including three Bundesliga titles (2002, 2011, 2012), two DFB Kup titles (2012,2017) and two SuperCup titles (2014, 2015). During his spell, some of the very best coaches in the world have been on the bench of this club including Jurgen Klopp and Thomas Tuchell.However, the most impressive thing that is connected to Zorc is his brilliant sense for selling the players. His strategy is to develop young players and introduce them on the big stage. The best example of that is Jadon Sancho, a player who is taking the whole world by storm this season with excellent games in the Black and Yellow shirt.This strategy has led Borussia Dortmund to various big-money transfers in recent years and latest of that kind is Christian Pulišić's transfer to Chelsea for £58 million. Other examples include Ilkay Gundogan, Mario Gotze, Henrikh Mkhitaryan, Piere Emerick Aubameyang, Ousmane Dembele and many others.Because of his brilliant business sense, he was wanted by Arsenal in the summer of the 2017 but he decided to stay with his childhood club.
