Bundesliga, gameweek seven: Preview, stats and key matches

Borussia Dortmund host an in-form Bayern Munich, with both sides having accumulated 15 points each after six games.

Dortmund forward Erling Haaland has netted all of his five league goals at home this season.

Bayern talisman Robert Lewandowski, who has 10 goals, will be in focus.

Notably, Dortmund have conceded the fewest goals (2), whereas, Bayern have scored a staggering 24 (highest).

Fourth-placed Leverkusen are unbeaten this season with three wins and three draws.

They take on Gladbach, who are placed fifth.

Forwards Lucas Alario and Marcus Thuram will be key for their respective sides.

This fixture has not finished goalless since April 2004.

Alario, who has scored in three successive Bundesliga matches, will hope to get his first career goal against Gladbach.

RB Leipzig, who are placed third in the table, are yet to lose at home this season.

Freiburg will be keen to notch a maiden win since their opening gameweek victory.

The worry for Freiburg is that they have dropped a league-worst nine points from winning positions this season.

Notably, Freiburg were unbeaten against Leipzig last season, winning one and drawing the other.

Mainz have lost all of their six league games so far this season and are stationed at the bottom.

Their opponents Schalke are placed 17th after collecting just two draws, besides losing four times.

Notably, Schalke are on a 22-match winless run in the Bundesliga.

They have also conceded the most goals this season (17), besides netting just thrice so far (fewest).
