Longest run of wins against a single opponent
The two Borussias have gone head-to-head a total of 92 times in the Bundesliga, with these matches witnessing a total of 309 goals - that makes for an average ratio of 3.4 goals per game. BVB have managed to score in each of their last 26 home games against Gladbach - the last time they failed to find the back of the net was a 0-0 draw in August 1988. Here's an overview of the facts.
The scenario: It's first against second. Dortmund have celebrated more wins than any other team in the league, emerging victorious from 12 of their 16 matches so far. Mönchengladbach have only lost one of their last seven matches. At this point last season, both teams had racked up a total of 25 points. Their respective performances this season therefore represent a significant improvement: with 39 points, BVB have 14 points more than they did a year ago, while VfL have eight more with 33.
Home and away: BVB are undefeated at home, winning 10 of their 12 matches at SIGNAL IDUNA PARK across all competitions. Borussia Mönchengladbach have just the one win in their last four away matches (3-1 in Bremen on 10 November), but have only been defeated three times on their travels. Only four teams in the Bundesliga have suffered fewer away defeats.
Personnel: BVB are missing three central defenders in Zagadou, Akanji and Diallo. Gladbach will have to make do without Doucouré, Ginter, Jantschke, Hofmann, Kramer, Stindl, Raffael and Villalba.
Head-to-head record: For the first time in the history of this Bundesliga fixture, one of the two sides has managed to put together a run of six consecutive wins - Borussia Dortmund! The Black and Yellows have come out on top in every match since the start of the 2015/16 season. This is the longest active run of wins against a single team. BVB have emerged victorious in 11 of the last 12 home games against the team from Niederrhein. Gladbach have thrown away a 1-0 lead against BVB a total of 22 times - a Bundesliga record.
Statistics: BVB have scored the most goals (42) and conceded the third fewest (17) in the league. The Black and Yellows have lost none of the last 22 matches in which they've taken a 1-0 lead. Mönchengladbach have scored three or more goals in seven matches so far this season.
Biggest win: It dates back to September 2012, when BVB ran out 5-0 winners. Marco Reus found the back of the net twice, with Neven Subotic, Ilkay Gündogan and Jakub Blaszczykowski also getting their names on the scoresheet.
Spectators: SIGNAL IDUNA PARK is completely sold-out, with a full capacity of 81,365.
Referee: 37-year-old Felix Zwayer from Berlin will take charge of a Bundesliga match involving Borussia Dortmund for the 22nd time.
