Bayern Munich's insatiable striker Robert Lewandowski struck twice as they saw off fellow Bundesliga side Hoffenheim 4-3 at home on Wednesday to reach the quarterfinals of the German Cup.
Holders Bayern fell behind when Jerome Boateng diverted a shot into his own net in the eighth minute but they soon levelled with an own goal by Hoffenheim's Benjamin Hubner before Thomas Mueller put them in front with a volley in the 20th minute.
Lewandowski stretched Bayern's lead further in the 36th minute and looked to have wrapped the game up when he struck again with 10 minutes remaining, netting for the 35th time in all competitions this season.
Yet Hoffenheim's new forward Moanes Dabour pulled a goal back for the visitors two minutes later and scored again in added time to set up a tense final few minutes.
Fourth-tier side Saarbrucken also reached the last eight of the competition after overcoming second-tier Karlsruher 5-3 in a penalty shootout following a goalless draw after extra time. Union Berlin beat Verl 1-0 and Bayer Leverkusen knocked out VfB Stuttgart with a 2-1 win to make it through to Friday's quarterfinal draw.
