Hoffenheim have only recouped one point from losing positions this term - fewer than any other team in the league.
Mainz have taken the lead in as many games as second-placed Bayern this term (14), but have only managed to win five of these matches and have dropped a league-high 22 points from winning positions.

Mainz have netted each of their last five league goals before the 19th minute.

1. FC Kaiserslautern - Borussia Mönchengladbach
This will be the 80th BL meeting between Lautern and Gladbach. Only against Bayern (47) and Hamburg (39) have FCK suffered more defeats in the top flight than against Borussia (38), while Gladbach have only enjoyed more wins over Köln (43) than over Lautern in the Bundesliga (38).
Gladbach have lost three and won only one of their last six matches against the Red Devils in all competitions; this coming when they beat Lautern 1-0 at home earlier this season.
Gladbach's last BL win at Fritz-Walter-Stadion came over 16 years ago when they beat the Red Devils 3-1 on the road in August 1995.
Only in one of their previous 44 BL campaigns have the Red Devils picked up fewer points after 21 games than they have this term (18) - in 2005-06 they had only accrued 17 points after the same number of games.
This game will see the team with the fewest goals conceded (Gladbach, 12) take on the team with the fewest goals scored (Lautern, 15).
Only four teams in BL history had netted fewer goals after 21 games than Lautern have this campaign (15). The last team that scored fewer than 15 goals 21 games into the season was Köln in 2001/02 (11 goals).
Only three teams in BL history had conceded fewer goals after 21 games than Gladbach have this term (12): Bremen 1987-88 (nine), Stuttgart 2003-04 (ten) and Bayern 2007-08 (11).
Lautern are winless in 11 BL games (seven draws, four defeats) - currently the longest run of its kind in the top flight. Their last win came over four months ago when they beat Freiburg 1-0.
Borussia have only lost one of their last 11 BL games (eight wins, two draws) and are unbeaten in their last five (four wins). Only leaders Dortmund (12) have won more points since the turn of the year than the Foals (ten).
Marco Reus has been directly involved in six of Borussia's nine league goals in 2012 (three goals, three assists).

Köln's last win away at Nürnberg in the Bundesliga came over 21 years ago, when they enjoyed an emphatic 4-0 win over FCN.
Only bottom-placed Freiburg (12) have suffered more defeats this term than Nürnberg and Köln (11 each).
Nürnberg have currently gone longer without scoring than any other team in Bundesliga (275 minutes) -their longest goal drought since autumn 2010 (289 minutes).
Köln have only netted three goals in their last six league games.
FCN have only been awarded two penalties this term - both were conceded by Pedro Geromel and converted by Timmy Simons in this season's first meeting between Nürnberg and Köln.
Köln have by far attempted the fewest shots in the league - only 8.4 per game on average.
The Billy Goats will miss their arguably most important player in Lukas Podolski due to injury. The German international has netted 52% of Köln's league goals this term.
Köln midfielder Martin Lanig formerly plied his trade with Nürnberg, while current FCN players Jens Hegeler, Markus Feulner and Hanno Balitsch all had stints with the Billy Goats.
Bayer Leverkusen - FC Augsburg
This will be Augsburg's first competitive game at BayArena.
All three previous competitive meetings between these two sides were played at Augsburg and have seen Bayer Leverkusen prevail (two times in the German Cup, once in the Bundesliga).
This season's first meeting of the two sides saw Hajime Hosogai open the scoring for FCA, but ended in a 4-1 win for Bayer (goals: Sidney Sam (two), Stefan Kießling and Eren Derdiyok).
With a victory over Augsburg, Bayer could become only the 11th team in the Bundesliga to break the 300 top-flight home win mark.
Bayer are without a win in three league games (two draws, one defeat) - their longest winless run since September 2010 (two draws, one defeat).
Augsburg have only taken two points from their last six BL games on the road. In total, FCA have only won one of their 11 BL away matches this term when they beat Mainz 2-1 in October.
No team has conceded more goals following set-piece situations than Augsburg (15, like Freiburg). Six of the last seven goals that FCA have shipped have come from dead-ball situations.
Bayer only attempted three shots in their 1-0 defeat at Dortmund last weekend - fewer than in any other BL game since 2004/05.
FCA defender Jan-Ingwer Callsen Bracker was under contract to Leverkusen between 2004 and 2008, making 36 BL appearances for Bayer (two goals), while Leverkusen-born FCA centre-back Dominik Reinhardt played for Bayer's youth teams.
FCA defender Sebastian Langkamp currently has the best duel rate in the league, having won 72% of his challenges this term.
Hamburger SV - Werder Bremen
This will be the 96th BL meeting between the two sides - no other BL fixture has been played that often. Werder are slightly in front of HSV in the head-to-head record having won 32 of the previous 95 duels, while Hamburg only enjoyed 30 wins over Bremen in the Bundesliga (33 draws).
Hamburg have won their last three BL home games against Bremen, but have lost their home games in the semi-finals of the German Cup (4-2 on penalties) and the semis of the UEFA Cup 2008/09 (3-2) against Werder during that period.
Hamburg have only lost one of their last 13 league games (five wins, seven draws).
Bremen have drawn each of their four league games since the turn of the year. The last time Werder drew four times on the bounce was back in 1998.
Thomas Schaaf's men have gone five BL games on the road without picking up a win (two draws, three defeats).
The Redshorts have only picked up 11 points from their 11 home games this term, but have taken 15 from their 10 games on the road and are the only side in the league apart from Hertha to have won more points on the road than on home soil.
Bremen have already recouped 17 points from losing positions this term - more than any other team in the Bundesliga.
Five of the last seven goals that Werder have conceded have came from headed shots. In total, Bremen have allowed their opponents nine headed goals this term - a joint league-high.
Claudio Pizarro has been directly involved in 20 of Werder's last 26 league goals (14 goals, six assists). The Peruvian striker has netted more goals against Hamburg than against any other team in the Bundesliga (14) and will be eligible again after missing Werder's last match due to suspension.
Hertha - Dortmund
In this season's first meeting between these two sides, newly promoted Hertha inflicted a shock defeat on Dortmund when they beat the reigning champions 2-1 on the road and leapfrogged them in the table. However, Dortmund are now 26 points and 14 places clear of the Berliners.
The meeting with Dortmund will be the 1000th BL game for Hertha. Last week's 5-0 defeat at Stuttgart was the 500th away game for the Berlin-based side.
With only nine points from their 10 games at Olympiastadion this term so far, Hertha are bottom of the BL home form table. They have only won two of their last 26 top-flight games on home soil (nine draws, 15 defeats).
Dortmund, on the other hand, have won more points on the road this term than any other team in the league (21).
This game will see the worst BL side of 2012 take on the best side since the turn of the year. While Hertha have lost all their four league games since Jan 1st, scoring only one goal in the process, Dortmund have won all their four league games in 2012, conceding only two goals in the process.
Jürgen Klopp's men have gone 15 games without defeat (12 wins, three draws) - currently the longest unbeaten run in the top-three tiers of German football.
Whenever Dortmund have picked up more than 45 points from their first 21 games of a BL season they have ended up winning the league (2011, 2002 and 1995).
Hertha's caretaker manager Rene Tretschok plied his trade with Borussia Dortmund between 1992 and 1997, winning two BL titles (1995, 1996) as well as the Champions League and the Intercontinental Cup (1997) with the Yellow-Blacks.
Borussia midfielder Shinji Kagawa has netted four goals in his last four appearances in all competitions.
Midfielder Raffael has scored in each of Hertha's four league wins this term. The Berlin-based side haven't won a single BL game this campaign in which the Brazilian hasn't found the back of the net.

Hannover have only lost one of their last seven BL home games against Stuttgart and have won their last two against the Swabians at AWD Arena.
In the corresponding fixture last season, the Reds beat Stuttgart 2-1 at AWD Arena. In the aftermath of that game Stuttgart sacked manager Jens Keller and replaced him with current VfB boss Bruno Labbadia.
