34 - Wolfsburg have never before picked up so many points in the first half of a season, not even when they won the Bundesliga title in 2008/09.

6 - For the sixth time this season on Matchday 17, SC Freiburg threw away a lead, also conceding an equaliser after the 85th-minute for the fifth time. Just like against Hoffenheim on Matchday 5, they let slip a two-goal advantage against Hannover 96 in 2014's final fixture.
