Cologne - When was the last time Borussia Dortmund endured such a terrible first half of the season? Which was the latest Bundesliga record to fall to the mighty FC Bayern München? And which club records have VfL Wolfsburg been breaking?

Matchday 17 provided a veritable feast of statistics, and has crunched the best of those numbers into some bite-sized portions for your delectation...

10 - Borussia Dortmund suffered a tenth defeat of the season, meaning they have now tasted defeat more in this Hinrunde than in any of the previous six seasons under Jürgen Klopp.

21 - Only 21 players have received a red card this season. The last time there were so few at this stage was in the 1989/90 campaign.

5 - For the fifth time in Bundesliga history, a team has gone the first half of the season unbeaten. With 14 wins and three draws, Bayern achieved the feat for the third time, with Hamburg in 1982/83 and Leverkusen in 2009/10 also going without defeat.

11 - FC Bayern München have an eleven-point lead over their closest pursuers, VfL Wolfsburg, after 17 games. Never before has a team gone into the Rückrunde with such an advantage.

9 - Hamburger SV have only scored nine goals this season. Only Tasmania Berlin (eight) in 1965/66 and Eintracht Frankfurt (eight) in 1988/89 have had worse goalscoring records at this stage of a season.

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.

14 - For the first time in 14 competitive games under Roberto Di Matteo, FC Schalke 04 drew.

7 - Bayer 04 Leverkusen have only won seven of 17 games in the Hinrunde. At this stage last season, they had 12 wins under their belt.

15 - With just 15 points, Dortmund have completed their worst Hinrunde since 1987/88.

5 - Alexander Meier has converted all five of his Bundesliga penalties.

4 - VfB Stuttgart failed to score on home turf for the fourth game in succession, equalling a club record. The south-west outfit have only ever experienced such a negative run once before: in 1999.

27 - With 27 points, FC Augsburg have set a new club record after 17 games. Never before have they racked up so many points at this stage of a season.

34 - Elkin Soto's goal for 1, FSV Mainz 05 against Bayern was only the second time the Bavarians have gone behind this season. The strike also made the 34-year-old Colombian the oldest goalscorer in his club's Bundesliga history.

350 - Sebastian Kehl's 350th game for Borussia Dortmund didn't quite go according to plan, as his side slipped to a 2-1 defeat to SV Werder Bremen.

6 - Max Kruse has scored each of his six Bundesliga penalties. His third-minute opener in the 2-1 defeat in Augsburg was Borussia Mönchengladbach's earliest goal for over two years.

4 - Bayern only conceded four goals in the Hinrunde, in the process setting a new Bundesliga record.

0 - Leverkusen are yet to lose a home game under Roger Schmidt. The BayArena has so far played host to four wins and five draws.

4 - Augsburg came back to win from a 1-0 deficit for the fourth time this season, a league high.

5 - Naldo joined Augsburg's Paul Verhagh on five goals with his header against 1. FC Köln. The duo are the league's highest-scoring defenders, while Naldo, with 36 league goals, is the highest-scoring defender among current top-flight players.

4 - For the fourth time this season, Köln lost despite taking a 1-0 lead - that's twice as many times as any other team.

2 - Freiburg have only won two games throughout this Hinrunde. Ten years ago, in the 2004/05 season, the Black Forest club achieved the same low.

2 - After a 1-1 draw in Wolfsburg on Matchday 15, SC Paderborn 07 drew 0-0 in Stuttgart on Matchday 17. For the first time ever, Andre Breitenreiter's men have gone two consecutive away games unbeaten.
