History against Billy Goats
Cologne must win their final two games to have a chance of staying up, but face Union and Heidenheim - the only two teams in the Bundesliga they have never beaten. In fact, there is no other team the Berliners have faced so often in the top flight without tasting defeat as Cologne (nine; W7, D2).
