Hannover had a good chance to take the lead when a cross came in from the left, but nobody could reach it.
However, the away side did go 1-0 ahead when Clemens Fritz was penalised for a foul in the box and the referee gave a penalty. Szabolcs Huszti dusted himself down and slotted the spot kick into the bottom corner.
An eventful first half continued when Salif Sane was given a yellow card for bringing down Eljero Elia and Werder had a penalty of their own. Aaron Hunt placed the ball on the spot and sent the goalkeeper the wrong way.
