The hosts remain bottom, but retain an outside chance of staying in the Bundesliga, while Hannover have now lost their last four league matches and are looking nervously over their shoulders in 13th place.
bundesliga.com rounds up the post-match reaction...
Ken Reichel: The fans were sensational, they supported us so well and the atmosphere was incredible. We all had goosebumps before the match. It was a lot of fun out there today and we definitely deserved to win it. We put so much into the game and never let our heads drop.
Havard Nielsen: It was a brilliant day for us and I was really happy with my performance. We're in a really good vein of form and we hope to keep it going.
Lars Stindl: Obviously we're disappointed. We started the game terribly and were 2-0 down after 20 minutes. We were never able to establish any rhythm and didn't create many chances. At 2-0 down it was hard to come back. We all know how serious the situation is. A defeat like this hurts more than other games. It's really frustrating for the fans who came here to support us with a lot of expectation.
Ron-Robert Zieler: We've lost 3-0 but I think we could have stopped all three goals. In the dressing room at the end of the game, there was just pure disappointment in the air - everyone was just too depressed. One win in nine matches is too little for us. Today was a painful, crushing defeat.
