• Four wins to start a Bundesliga season is something Dortmund have only managed once before; back in 2001/02, when they won the title. A draw would be enough for Dortmund to set an club record for a start to a season.
  • Dortmund have the chance to become the 12th team in Bundesliga history to start a season with five consecutive wins. The last team to achieve that was Bayern last season, as they went on to set a new record, winning the first eight games.
  • In the 2012/13 season, HSV managed to beat Klopp's men twice in the Bundesliga (3-2 at home and 4-1 in Dortmund). The 3-2 defeat in Hamburg on matchday 4 brought Dortmund's run of 31 Bundesliga games without defeat to an end.
  • Henrikh Mkhitaryan scored his first two Bundesliga goals in the 2-1 win in Frankfurt. Götze's replacement is the first Armenian to score in Germany's top flight.
  • Rafael van der Vaart has lost only one of his six encounters with Dortmund. He has won his last five games against Dortmund, scoring two and assisting three in the process.
  • In the 4-0 win against Braunschweig, Hakan Calhanoglu celebrated a scoring Bundesliga debut. His second goal came from a direct free kick; the first HSV player to score one in over a year and a half (Mladen Petric scored against Bremen in February 2012).
  • Since their 1-0 defeat in Gladbach back in April 2011, Dortmund are undefeated in 11 Saturday evening games (seven wins, four draws). At home, Klopp's team have not lost any of their Saturday evening games; that were introduced back in 2009, winning nine and drawing three.
  • HSV, on the other hand, are without a win since January 2011 (1-0 in Schalke) in 11 Saturday evening games (five draws, six defeats), and have even lost the last five they've contested.
