Borussia Dortmund have lost only one of their last ten matches against Mainz (eight wins, one draw) and have conceded an average of under one goal per game (17 in 18) against the 05ers - they only have a better defensive record against Ingolstadt. Here are the facts for Friday's match.

First goal of decisive importance

  • BVB have never lost a match against Mainz after scoring the opening goal (six wins, four draws).
  • Borussia have won the last 12 matches in which they have broken the deadlock. The last time they dropped points after scoring the opener was in a 2-2 draw with Wolfsburg on 17/12/2014.
  • Mainz have won the last six matches in which they have scored first. The last time they dropped points after scoring the opener was in a 1-1 draw with Wolfsburg on 22/3/2015.

Action-packed

  • Five penalties have been awarded in the last four matches between BVB and FSV (three in Dortmund's favour, two for Mainz).
  • There have been goals galore in games involving Borussia Dortmund this season: 33 in total - more than any other team in the Bundesliga.

Facts on Mainz 05

  • Mainz have only kept a clean sheet in one of their last nine games (in a 3-0 win against Hannover 96 on 29/8/2015).
  • The 05ers have already suffered two home defeats this season - last year they were still unbeaten at home after eight games.

Facts on Borussia 09

  • The Black and Yellows have fewer yellow cards than any other Bundesliga side so far this season (seven).

Personnel matters
