Overview
- Borussia Dortmund drew 0-0 away to Union Berlin and remain top of the Bundesliga but their lead is vulnerable to a Bayern win in a game in hand.
- Dortmund controlled possession but created little threat, registering 64% of the ball, six shots and only one on target.
- Substitute Konstantinos Karetsas suffered a serious-looking ankle injury and was helped off the pitch minutes after coming on, raising fresh squad fitness concerns.
- Promoted Elversberg continued their surprising start with a narrow home win over Augsburg, though sources disagree on the exact scoreline, and Mainz moved into the top five with a 1-0 win at Schalke.
- Dortmund began the season with a six-match winning run but have since drawn twice and lost once, a run of form that tightens the early title race and will test their depth across coming league and European fixtures.
