Facts and figures ahead of Sunday's Bundesliga action, with Dortmund hosting Hannover.

Borussia Moenchengladbach v Hamburg

Borussia have won four of their last six BL games against Hamburg (D1, L1) including this season’s first meeting when Gladbach beat HSV 1-0 courtesy of an Igor de Camargo goal. It was the last match in charge of the Redshorts for former HSV manager Michael Oenning who was sacked in the aftermath of that game.

Only once in their BL history have the Foals accrued more points after 22 games than they have this term (46): When they won the league in 1969-70 they had registered 51 points after the same number of games (adjusted to the three-points rule).

Only three teams have ever conceded fewer goals after 22 games of a BL season than Gladbach have this campaign (13): Bremen 1987-88 (10), Stuttgart 2003-04 (ten) and Bayern 2007-08 (11).

Gladbach are unbeaten in six games (W 5, D 1) – only Dortmund (16 games) and Hannover (nine games) have currently gone longer without defeat.

Gladbach and Hannover are the only two sides in the league yet to lose a home game this term. The Foals have now gone 14 league home games without defeat – currently the longest run of its kind in the Bundesliga.

Last week’s 3-1 defeat to Bremen was only the second defeat for Hamburg in the 13 BL games since Thorsten Fink took charge of the team (W 4, D 7). The Redshorts have lost none of their last seven league games on the road (W 4, D 3) – only reigning champions Dortmund have gone longer without defeat away from home (nine games).

The Foals have scored the fewest goals in the current top four (36), but boast the best defensive record in the league with only 13 goals conceded.

Foals manager Lucien Favre has only lost one of his six BL encounters with HSV (W 2, D 3). HSV gaffer Thorsten Fink only lost three of his 18 BL games against Gladbach during his playing career (W 9, D 6).

Gladbach-born HSV midfielder Marcell Jansen joined Borussia in 1993 and signed his first professional contract with the Foals in 2004. The German international made 73 BL appearances for Gladbach between 2004 and 2007, scoring five goals in the process.

Bayern Munich v Schalke

Schalke have suffered more defeats (40) and conceded more goals (168) against Bayern than against any other team in the Bundesliga.

The Gelsenkirchen-based side have only lost one of their last five matches in all competitions (W 2, D 2), but lost their last BL outing at Bayern 4-1 last season.

In 1976-77 Schalke beat Bayern 7-0 on the road. That 7-0 drubbing is still Bayern’s heaviest defeat in the Bundesliga and Schalke’s biggest win in the German top flight.

In April 2009 Schalke won at the Allianz Arena for the first time when they beat Bayern 1-0. In the aftermath of that defeat Juergen Klinsmann was sacked as Bayern manager.

FCB have won nine of their last ten league games at Allianz Arena (L 1). Only upcoming opponents Schalke (28) have accrued more points at home this term than the German record champions (27).

The Royal Blues have only lost one of their nine BL games following a midweek Europa League match (W 7, D 1).

Only Schalke (50) have scored more goals so far this term than Bayern (49).

Bayern’s Mario Gomez and Schalke’s Klaas-Jan Huntelaar currently share the lead in the BL scorer charts (18 goals each).

Jupp Heynckes (2003 – September 2004), Manuel Neuer (1991-2011) and Rafinha (2005-10) have all formerly been under contract to Schalke, while Schalke’s Alexander Baumjohann plied his trade with Bayern between summer 2009 and January 2010.

Current S04 manager Huub Stevens was sacked as Hertha gaffer in December 2003 following a 3-1 defeat against a Schalke side managed by Jupp Heynckes. Schalke’s next league goal will be their 300th in Huub Stevens’ two stints with the club.

Borussia Dortmund v Hannover

Hannover have only won of their last seven BL encounters with Dortmund (D 3, L 3) when they came bach from 1-0 down courtesy of late goals by Karim Haggui and Didier Ya Konan to beat the reigning champions 2-1 in this season’s first meeting between the two sides.

The last six BL duels between Hannover and Dortmund have seen a total of 27 goals – an average of 4.5 goals per game.

This match will see the two teams with the longest current unbeaten runs take each other on. Hannover have gone nine games without defeat, while league-leaders Dortmund suffered their last defeat in this season’s first meeting with Hannover and haven’t lost any of their 16 BL games since.

Borussia have won their last six games on the bounce and could equal the club record for the most consecutive wins in the Bundesliga with a victory over Hannover. BVB have managed to win seven games in a row three times before – they achieved that feat twice last season and once in 2008-09.

Hannover are unbeaten in their last five BL games on the road, but have only enjoyed one win in their last ten league games away from AWD Arena (D 5, L 4) and have failed to score more than one goal in any of these matches.

Dortmund haven’t conceded a goal in 387 minutes in all competitions. The last team to score against the reigning champions was Hoffenheim at the end of January. If BVB shut out Hannover they will have gone the whole month of February without conceding a single goal.

The Reds have lost none of their nine BL games following a midweek Europa League match (W 4, D 5).

Dortmund have netted at least once in each of their last 18 BL games – currently the longest run of its kind in the league.

With 49 (Dortmund) and 34 points (Hannover) respectively both teams have registered their second-best ever points haul after 22 games in the Bundesliga. The only campaign in which both sides had accrued more points after the same number of games was last season when Dortmund had won three and Hannover had won four more points than they have this term.

BVB midfielder Sven Bender has won an average of 2.26 points per game in his so far 66 BL appearances – the best points-per-game average by any BL player with at least 50 BL appearances.

Christian Pander scored one and assisted two goals for Hannover in the Reds‘ 4-2 win over Stuttgart last weekend and could make his 100th BL appearance against Dortmund.
