Germany manager Joachim Low has described his side's shock 1-0 defeat away in the Republic of Ireland as "unexpected and totally unnecessary".
The world champions were undone by a solitary goal from Shane Long in the 71st minute at the Aviva Stadium.
Low told BBC Sport after the game: "It was an unexpected and totally unnecessary defeat.
"In the second half we played a bit negligent. Ultimately, we lacked the ultimate consequence and the last pass. And then we make a single mistake and it is a goal."
Germany remain at the top of Group D on 19 points with one game left to play.
