Joachim Low has said that he is not worried by Germany's 5-3 loss to Switzerland on Saturday.
The 52-year-old said that he was disappointed with the results and blamed poor communication and a lack of match fitness.
However, Low believes that there is still plenty of time to get things right ahead of Euro 2012.
"We are disappointed with this result," said Löw. "We knew that we would be lacking freshness ahead of this game after intensive training sessions over the last few days.
"Our communication was poor and thus we conceded five goals. It was only a friendly match and there's a lot to be learned from this game.
"We made a lot of mistakes, but we still have two weeks and I'm not worried."
Low took charge of the national side following Jurgen Klinsmann's departure in 2006.
