This is the new official Germany away football kit for the 08/09 season and euro 2008 made by Adidas. Pictures of the shirt were leaked back in December 2007 and caused some debate because its not green.. The kit is based on a kit used 100 years ago in 1908.
The away shirt colour has changed several times. Historically, green shirt with white shorts is the most often used alternative colour combination, derived from the DFB colours (and the ones of a playing field). Other colours such as grey and black have also been used.
The last change, from black to red, came in November 2004 on the request of Klinsmann, citing that teams in red are statistically more successful, and perceived as more intimidating. He hoped to use the red away shirt as first choice for the 2006 World Cup despite less than impressive results when playing in these colours (for example, the 1-4 loss in Italy), but eventually Germany played in its traditional colours.
The green away jersey comes from the fact that the DFB's (Deutscher Fußball-Bund) official colour is green yet a very common myth associated with Germany's use of a green-coloured away jersey is in recognition of the fact that Ireland were supposedly the first nation to play Germany in a friendly game after World War II. This is false. Their first match after WWII was in fact against the Swiss.
