German Bundesliga Opta Facts 12-14 Feb
Mainz have won just four of their 19 Bundesliga games against Schalke (D4, L11) - in fact only Bayern have beaten them on more occasions in the top flight (14).
The 05ers have won just one of their last seven home meetings with S04 (D2 L4) - 2-0 in April 2015, a game which also took place on a Friday.
Martin Schmidt's men have won their last two games, keeping successive clean sheets in the process. This is their longest run of victories since 2013/14 (3) - they have never won three on the spin without conceding.
Andre Breitenreiter's side have won four of their last six league games, including each of their last two. They have scored in their last 12 Bundesliga fixtures - the longest run of such in the division.
S04 netted two goals on the break vs. VfL last weekend and have scored a league high nine goals in this manner in 2015/16. They scored just two such goals in the whole of last season.
Last weekend saw Schalke score three long-range goals in a match for the first time in a game since detailed statistics began being collected in 2004/05. Their total tally for 2015/16 stood at one before the VfL match (Max Meyer vs. Bayern).
Jairo Samperio has been directly involved in each of FSV's last five goals (3 goals, 2 assists). The Spaniard has scored as many goals in his last six Bundesliga appearances as in his previous 34 (3).
Christian Clemens, who has been on loan at Mainz from Schalke since January 2015, has had a hand in each of FSV's last three goals (2 goals, 1 assist). He has never come out on top against his parent club (L4).
SV Werder Bremen average more points per game against TSG 1899 Hoffenheim (2.13) than against any other current Bundesliga side.
TSG have never won in Bremen (D3, L4). Darmstadt are the only other current top-flight team yet to claim all three points in the city (D1, L1).
This match will be the fourth this season between two sides in the bottom three. All of the previous three basement battles have gone the way of the visitors.
Bremen have claimed a league low five home points this term and are without a win in seven in front of their own fans (D2, L5). Failing to win this weekend would result in a new negative club record.
14 points is TSG's worst ever return at this point of a Bundesliga season. Indeed, all other Bundesliga sides have won at least twice as many games this season as the side from Baden-Württemberg (2).
No side has conceded more goals than Bremen this season (41, level with Stuttgart). They've failed to keep a clean sheet in their last 23 league outings - the longest current such run in the division and a negative club record.
Hoffenheim have won just one away game in 2015/16 (D3 L6).
Claudio Pizarro is the Bundesliga's top scorer in 2016 (4, same as Meier and Lewandowski). He is also the first Bremen player since Ailton in 2000/01 to score in each of the first three league games of a new calendar year.
Kevin Volland has not scored in 807 minutes of Bundesliga action, and has never come out on top against Bremen in the top flight (D3, L4).
SV Darmstadt 98 - Bayer 04 Leverkusen
Darmstadt's first Bundesliga win for 33 years came in the reverse fixture (1-0 courtesy of Aytac Sulu's eighth minute strike).
Bayer 04 lost on their last trip to Darmstadt - Michael Blättel grabbed the winner in a DFB Cup second round tie in September 1989 (1-0).
With 17 points, Darmstadt sit third in the away standings this season. However, they find themselves 16th in the home rankings with just seven points from 10 home games.
The Lilies have won just once at home this season (D4, L5). They haven't scored in any of their last three home league games - a negative club record (D1, L2).
B04 are unbeaten in five league games - their longest run of 2015/16 (W3, D2).
Both of Darmstadt's goals in the 2-0 win over TSG last time out came from corners. They've scored 12 goals from set pieces this season - a league-high.
Darmstadt will face European competitors in five of their next seven league matches: Leverkusen (MD21), Bayern (MD22), Dortmund (MD24), Augsburg (MD26) and Wolfsburg (MD27).
Aytac Sulu scored his fifth goal of the season against Hoffenheim. He has opened the scoring with a header on four occasions this term.
Hakan Calhanoglu scored an 89th minute free kick for Karlsruhe against SVD in 2012/13 (third division). KSC were promoted at the end of the season.
Stefan Kießling has scored against 16 of the current 18 Bundesliga sides -Darmstadt 98 and FC Ingolstadt are the only exceptions.
Borussia Dortmund - Hannover 96
The sides meet in the Bundesliga for the 50th time this weekend - BVB have won 24 of the 49 to date, including nine out of the last 12 clashes (D1, L2).
However, the Reds claimed the points on their last visit to Dortmund (1-0 in October 2014).
Hannover have only been in a worse position at this point of a Bundesliga campaign once before. In 1971/72 they also had 14 points (converted to three-points-for-a-win), but their goal difference was weaker.
12 of the 15 teams who have had just 14 points after 20 games have been relegated (partially converted to the three-points-for-a-win system). The only exceptions are Augsburg (2012/13), Oberhausen (1971/72) and Hannover (1971/72).
BVB have 25 points from their opening nine home games this term (joint club record) - a win this weekend would see them break the previous benchmark.
Borussia are unbeaten in 13 Bundesliga home games (W12, D1), scoring at least twice in each of those games - their best run since 1980-81 (14).
Tuchel's men have the best tally for a second-placed side in the history of the Bundesliga after 20 games (45) - they're still eight points behind FCB.
H96 are on a run of six straight Bundesliga defeats for the fifth time - only Nürnberg can match this. The last time they went on a longer run without a win was in 2009/10 (9).
Thomas Schaaf has lost on his last seven trips to Dortmund (F2, A13). He's yet to claim a point as Hannover boss (3 games) - his worst opening run as a Bundesliga boss.
Oliver Sorg lost all seven of his games against BVB - only Bernd Dreher and Sebastian Prödl have faced Dortmund on more occasions without claiming a point (both 8).
Hertha are unbeaten in four league games vs. Stuttgart (W3, D1). VfB's last win dates back to September 2013 (1-0 in Berlin).
Both sides are unbeaten in six Bundesliga games - the longest runs in the division.
VfB have won each of their last four Bundesliga fixtures, their longest run since early 2010 (6). Berlin are yet to secure a victory since the winter break though (D3).
Only two sides have picked up more points than VfB (14) since Jürgen Kramny took over - FCB and BVB (16 each). Stuttgart top a table representing the past six matchdays.
VfB Stuttgart have become the only team in Bundesliga history to begin the first half of the season with three straight defeats and begin the second half with three consecutive victories.
Hertha BSC already have as many points on the board this term as they accrued in the whole of last season (35). VfB have six more points than they did at this stage of last season.
Salomon Kalou has scored eight of his 10 Bundesliga goals this term on the road - a league high. He averages a goal every 87 minutes away from home.
Daniel Didavi is Stuttgart's top scorer this season (9), though he misses this game through suspension.
Jürgen Kramny faced Hertha BSC five times as a player during spells with Stuttgart, Mainz and Nürnberg (W2, D3).
The sides drew 0-0 in the reverse fixture. VfL won the only other previous competitive meeting, in the last 16 of the 2013/14 DFB Cup.
The Wolves are winless in seven Bundesliga games (D3 L4), the longest such current run in the division, and their longest such run since 2012.
Die Schanzer are the only Bundesliga side without a win in their last seven away games. They've lost their last three and are without a goal in 411 minutes on the road.
FCI have 26 points despite scoring just 14 goals. No other Bundesliga side has claimed as many points at this stage of a campaign after netting so infrequently.
Dieter Hecking's men have scored in each of their last 40 Bundesliga home games and could equal a club record this weekend. Only three teams have gone on longer streaks in the division's history - FCB hold the overall record currently (64).
Only Bayern (6) have conceded fewer away goals than Ingolstadt this season (11).This is a record low for a Bundesliga debutant after 10 away games.
VfL conceded from a dead ball during the 3-0 defeat to S04, meaning every side has now let in a goal in this manner in 2015/16. FCI have conceded a joint-league-high 57% of their goals from set pieces (level with Darmstadt).
The Wolves are unbeaten in eight Bundesliga games against newly promoted sides (W4, D4) but have only won two of their last 14 home matches against these teams (D6, L6).

With 2.2 points per game on average, Frankfurt have the best record in Saturday evening games of any side in the league. Köln have won just one of 15 games on Saturday evening (D5, L9), leaving them bottom of the standings with 0.5 points per game on average.
SGE have 21 points - five fewer than at this point of the 2010/11 season, a campaign which ended in relegation.
Anthony Modeste has been involved in 52% of Köln's 21 goals this season (9 goals, 2 assists) - proportionally speaking a league high.
Alex Meier has scored seven goals in his last three appearances against Köln. The forward netted a brace in both meetings last season, before scoring his first-ever Bundesliga hat-trick in this term's reverse fixture.
Armin Veh will take charge of his 300th Bundesliga match this weekend. His highest win in the division came in the reverse fixture (6-2, also won by a four-goal margin on five further occasions).
Peter Stöger didn't make any substitutions last weekend - the first time this has happened in the Bundesliga in 2015/16. Only Bayern (7) and Wolfsburg (6) substitutes have scored more goals than Köln replacements this campaign (5).
Hamburger SV - Borussia Mönchengladbach
Gladbach have lost just one of their last six Bundesliga games at the Volksparkstadion (W3, D2).
Hamburger SV are winless in six league games (D2, L4), their second-longest run without a win under Bruno Labbadia (7 in 2009).

Ahead of last weekend's 5-1 rout of Bremen, Borussia had lost five of their previous six competitive games (W1).
The Foals are without a win three on the road (D1, L2), including defeats without scoring in their last two (5-0 in Leverkusen, 1-0 in Mainz).
Only Bremen (23 games) have waited longer for a clean sheet than HSV (10). However, they have netted in 10 of their last 11 matches.
The Foals have netted 38 times since Andre Schubert took charge - a league high in this time period. Additionally, Gladbach's nine goals from distance this term is a league high.
21 of the 28 goals HSV have shipped have come in the second half of games - proportionally, a league high (75%). 10 of these 21 goals were conceded in the last 15 minutes - only Frankfurt have let in more goals in the same period (11).

The sides have met 11 times competitively since Augsburg were promoted to the Bundesliga in 2011, with two wins for Augsburg and nine for Bayern.
Only FCA and BMG have beaten Guardiola's FCB more than once in the Bundesliga. He is yet to lose three league games to a club as a head coach (including at Barcelona).
Bayern had to settle for a draw in Leverkusen after four consecutive Bundesliga victories. However, no side has claimed more points than them in that timeframe (13, same as VfB).
Augsburg have claimed just two points in 2016. They've scored just once in that timeframe (a league low together with Hoffenheim and Hannover).
Bayern recorded just nine shots in Leverkusen and only 77% of their passes reached teammates - both season lows for Pep Guardiola's men.
Bayern have 53 points from 20 games - the second best return at this point of a Bundesliga campaign to date. They also hold the record tally (56, 2013/14). They have let in just nine goals so far this term - the previous best was seven (also set by Bayern, 2012/13).
