Deuter Müller is Germany's first choice keeper, known as the "Phantom Keeper" and, subsequently, the "Steel Giant".

Muller had earned a legendary status in his home country even before his debut for Germany Jr. Youth in the Junior Youth tournament in France. He has been one of the German side's main players since.

Due to the severe training on a mountain, Muller is exceptionally strong and tough and remarkably agile for his size. His mere presence in goal gives an impression of impenetrability and he has backed this up by conceding only under extreme circumstances.
