Just as Dortmund were about to rally back, Dan-Axel Zagadou committed a last-man foul to Jonathas to see a straight red car in the 59th minute. To make things worse, Felix Klaus utilized the subsequent free kick to score the 3-2 lead with the hour mark.

Dortmund kept it bowling but Hannover made the game safe in the 86th minute when Bebou wrapped up his first-ever career brace following a counter attack.

With the result, Dortmund lose their top spot after failing to reap a win in their third consecutive Bundesliga clash while newly promoted Hannover jumped on the 4th place.

Bayern Munich took advantage on Dortmund's defeat and moved atop the standings for the first time of the season as the German record champions beat Leipzig 2-0 on the goals from James Rodriguez and Robert Lewandowski.

Leipzig caught the worst possible start on the road as Willi Orban received his marching orders with only 12 minutes played after the defender committed a professional foul to Arjen Robben.

The game was already over for the visitors especially when James Rodriguez tapped home a square pass from Robben to break the deadlock in the 19th minute.

Bayern continued on the front foot and added another goal to their lead in the 38th minute as Robert Lewandowski made use of Javi Martinez' through ball to make it 2-0.

Leipzig increased their efforts after the restart but Bayern retracted and protected their two-goal lead to the end to grab their place in the front seat of the Bundesliga standings.
