The Revierderby between Borussia and Schalke, both located in North Rhine-Westphalia, Germany is the Bundesliga's first derby dating back to 1925.
Both clubs have had periods of dominance, and neither set of fans is above celebrating the other's failures. In May 2007, Schalke lost to the derby and by doing so the league lead, for which Borussia made commemorative shirts, and in 2008, Borussia fans celebrated 50 years since Schalke had won the league title. But Schalke was able to shove the Champions League in their neighbor's face this season.
