BVB dominated possession (69%) as expected against a St. Pauli side that defended cleverly and passionately, but they did not come up with enough in the final third.
Upshot: Borussia Dortmund were even more dominant than they had been in the first half after the break and had twice as many shots at goal as their hosts (8-4), but aside from the penalty kick, really good opportunities were few and far between against the passionately defending Kiezkicker.
Slip-up: BVB have been eliminated from the cup by a lower-league team for the first time in over 11 years. The last time was under Jürgen Klopp in 2010/11, when they were knocked out by then third-tier Offenbacher Kickers on penalties.
Next favourite eliminated: The Bundesliga's current top three (Bayern Munich, Borussia Dortmund and Bayer Leverkusen) will not be involved in the last eight. It will be the first time in 15 years without Bayern Munich and Borussia Dortmund in the cup quarter-finals, and the DFB-Pokal final will be the first in 11 years (Schalke faced Duisburg in 2010/11) without either Bayern or Borussia in it.
Haaland's scoring run: Erling Haaland has now scored 79 goals in 78 competitive games for Borussia Dortmund. He also has more goals (eight) than games (seven) in the DFB-Pokal. He has six goals in his last three cup games alone: two in last year's final, three in this season's first-round encounter in Wiesbaden and now one at Millerntor.
Witsel follows Wörns: It was the first own goal scored by a Borussia Dortmund player in the DFB-Pokal since October 1999, when Christian Wörns put the ball into his own net away to Stuttgarter Kickers.
