Despite ending last season with some impressive performances for Werder Bremen, Frings was not included in Germany's provisional 27-man squad for the 2010 FIFA World Cup South Africa, but his name has been mentioned as a possible replacement for Ballack, who will miss the tournament due to a foot injury.
But Frings told the Bild newspaper: "I simply don't have any faith in the national team coach anymore. That has not changed after the tragic injury to Michael Ballack either. Therefore, whatever happens, I am not available."
