• Dortmund have lost in five of their last seven trips to Hamburg (W1 D1).
  • HSV have lost their last eight competitive matches – their last Bundesliga win was at the end of November against Hannover (3-1), who at the time were being managed by Mirko Slomka.
  • Hamburg have never conceded as many goals after 21 matches as they have currently (51). Dortmund, on the other hand, have scored 51 goals – the last time they scored as many after 21 games was in the debut Bundesliga season in 1963/64 (57).
  • Never before in 51 years of the Bundesliga have Hamburger SV had so few points after 21 matchdays than they currently do (16).
  • HSV are bottom of the home table with just seven points collected in their own stadium. The league's weakest home side has been relegated in each of the last 15 seasons. The last team to defy that statistic was Hamburg themselves back in 1997/98.
  • Goalkeeper Rene Adler gifted two goals in HSV's 4-2 defeat to Braunschweig. Adler is the worst player in the league in this regard, making four mistakes that have led to goals.
  • Pierre-Emerick Aubameyang has scored five times in his last four competitive matches. He has scored the opening goal on six occasions this season – a league high together with Adrian Ramos.
  • Mirko Slomka is the new HSV manager. He took over at his former side Hannover on matchday 19 of the 2009/10 season with the club in 16th place and, despite starting with six defeats (joint Bundesliga record), achieved Bundesliga survival.
  • This is Jürgen Klopp's 12th meeting with HSV since he took over at Dortmund in the summer of 2008. Mirko Slomka will be the sixth different Hamburg manager he will have faced.
  • Klopp celebrated his 111th Bundesliga win with BVB last weekend, matching the club record held by Ottmar Hitzfeld.
