High Quality Content by WIKIPEDIA articles! You have to win Zweikampf is the sixth studio album released by the German rock band Sportfreunde Stiller. It was released on May 19, 2006, only a few weeks before the opening of the 2006 FIFA World Cup that was being hosted in Germany. The album is a concept album focused around Association football. Football has featured prominently in the band previous releases (cf. "10:1", So wie einst Real Madrid), but this was their first album with solely football-related tracks.
