Goetze treble spurs Dortmund
Mario Goetze scored a hat-trick as holders Borussia Dortmund marched into the quarterfinals of the German Cup with a 5-1 thrashing of Hanover on Wednesday.
Wolfsburg joined them in the last eight after coming from behind to beat Bayer Leverkusen 2-1, while VfB Stuttgart defeated second-division side Cologne 2-1.
Bochum ran out 3-0 winners over 1860 Munich who had Spanish defender Guillermo Vallori sent off for a foul in the 27th minute in a meeting of two second-division sides.
Bundesliga champions Dortmund were in early command against visiting Hanover when Germany midfielder Goetze scored from close range in the third minute.
A second followed in the 18th when Poland midfielder Jakub Blaszczykowski took a pass from Marco Reus and overcame keeper Ron-Robert Zieler at the second attempt.
Goetze added his second and Dortmund's third five minutes before the break with a direct free-kick outside the area which he hit low under the Hanover defensive wall.
It was a champagne first-half from Juergen Klopp's side who continued to sparkle after the break but lacked the precision of the first half until Goetze and Robert Lewandowski bagged two late goals.
Hanover had made Dortmund pay for a loss of concentration when Mame Biram Diouf headed in a Szabolcs Huszti cross in the 79th minute.
But the reply was not long in coming, Lewandowski crossing from the left of the area for Goetze to volley in at the far post five minutes later before the Poland striker netted himself in the last minute.
In Wolfsburg, Dutch striker Bas Dost scored a last-minute winner for the home side who were chasing the game after Brazilian defender Fagner turned the ball into his own net in the 31st minute.
An over-cautious Leverkusen paid for their lack of ambition when Christian Traesch came off the Wolfsburg bench in the 75th minute and three minutes later fired in a powerful first-time shot from the edge of the area.
Wolves' winner came when Leverkusen defender Omer Toprak could only head a long ball from Ivica Olic into the path of Dost, who rifled the ball past keeper Bernd Leno.
The victory was a boost for caretaker coach Lorenz-Guenther Koestner in what could have been his last game in charge since filling on following the departure of Felix Magath in late October.
Koestner would like to stay on, although a report in Germany's Bild newspaper Wednesday said former German international Bernd Schuster was now a candidate for the Wolfsburg job.
"As long as I am needed and nothing to the contrary is said I will do it," he said. "I am an interim coach. I have not demanded anything and am not demanding anything today."
Stuttgart progressed thanks to first-half goals from Christian Gentner and Vedad Ibisevic from the penalty spot against second-division Cologne, who pulled one back through Christian Clemens in the 80th minute.
On Tuesday, Bayern Munich, Mainz, Freiburg and third-division Kickers Offenbach booked their places in the last eight.
