リテックス・ロヴェチ
Union again came close to advancing to 2. Bundesliga in 1998–99 and 1999–2000, but were disappointed. They were finally successful in 2000–01, under Bulgarian manager Georgi Vasilev, easily winning the Regionalliga Nord (III) and moving up a division to become the city's second most popular side. That same year they appeared in the final of the German Cup where they lost 0–2 to FC Schalke 04, and advanced as far as the second round in UEFA Cup before being put out by Bulgarian side PFC Litex Lovech. The club slipped to the Regionalliga Nord (III) in 2004–05 and then to the NOFV-Oberliga Nord (IV) in 2005–06, but returned to third division play after capturing the Oberliga title. In 2008–09, Union became one of the founding clubs of the new 3. Liga, and its inaugural champion, securing first place and promotion to the 2. Bundesliga on 10 May.
