"France will be among the Euro favourites, just like Spain and Germany," said Germany coach Joachim Low after watching his team lose in the Bremen friendly.
France looked impressive in counter attacks, with full-back Mathieu Debuchy and winger Mathieu Valbuena proving a strong threat throughout.
Lille's Debuchy set up Olivier Giroud's and Florent Malouda's goals as the visitors, who for once were playing a team wanting to do more than sit back and wait, surprisingly outplayed three-times European champions Germany.
"These are friendlies, of course, but England, Brazil or Germany are prestigious opponents," said Blanc, referring to France's victories over England in 2010 and Brazil last year.
"We showed that we were able to compete with one of the best teams in Europe," said midfielder Yohan Cabaye.
"This kind of victory will help us prepare for the Euro finals peacefully," added centre-back Philippe Mexes.
"This victory is important for our self-confidence but let's not get carried way," the Olympique Lyon keeper said.
"We will also monitor the players' performances with their clubs but those who were here tonight have scored points," he said.
Giroud, the Ligue 1 top scorer, also shone at the Weser Stadium and he could well be the third striker for the Euro finals along with Loic Remy and Karim Benzema, who both missed Wednesday's game through injury.
