Borussia Dortmund faced a frustrating 0-0 draw against Werder Bremen in the Bundesliga, highlighted by defender Nico Schlotterbeck receiving a red card in the 73rd minute for a second yellow card due to a tackle on Justin Njinmah. Despite Dortmund's dominance in possession and some aggressive plays, including a long-range effort from substitute Karim Adeyemi, they struggled to convert their chances, managing only four shots on target. Meanwhile, Stuttgart was denied a first win of the season as Maxim Leitsch scored a late equalizer for Mainz to secure a dramatic 3-3 draw. Stuttgart had previously led 2-0 but allowed Mainz to equalize before conceding a late goal in their match. In other matches, newly promoted Holstein Kiel lost 2-0 to Wolfsburg, and Borussia Moenchengladbach secured a 2-0 victory at Bochum. Dortmund's struggle to score marks a concerning trend as they prepare to face Heidenheim next.
