Wolfsburg continued their dominance at home in beating 10-man Hannover but needed the help of an own goal by Jiri Stanjer.
Christian Zaccardo opened the scoring in the 32nd minute and Stanjer equalized in the 59th minute.
But the Hannover defender scored an own goal in the 63rd minute. Hannover keeper Florian Fromlowitz was sent off with a red card in the 80th and Edin Dzeko failed to converted the resulting penalty two minutes later.
Zaccardo scored the opener nine minutes later after some fine passing by the Wolfsburg attack.
Zvjezdan Misimovic played a one-two into free space right of goal and then passed back to the Italian defender, who hit home from six yards out.
Wolfsburg nearly doubled the advantage on 36 minutes as Dzeko had space from seven yards but could not beat Fromlowitz.
Hannover's best chance came two minutes before the break as Mike Hanke was quicker than Andrea Barzagli to a long ball and tried to poke it past Diego Benaglio, but the Wolfsburg stopper blocked the shot and Barzagli cleared the loose rebound.
Stanjer equalized in the 59th minute. Konstantin Rausch's long high cross from the left went past two Hannover players in the area but a charging Stanjer was there to blast home from 12 yards.
Stanjer scored another goal just four minutes later - but into his own goal. Misimovic sent a free-kick from the left into the area and Stanjer headed back a ball which Fromlowitz was unable to collect at the far right post.
Fromlowitz was sent off with a red card with 10 minutes left after taking down Dzeko in the area.
Hannover midfielder Jan Rosenthal stepped between the posts and dove to his left to divert Dzeko's penalty off the post.
