Borussia Dortmund faced another setback on Saturday, succumbing to a 3-1 defeat against Mainz. This marked their fourth consecutive away loss. Despite a recent Champions League win over Sturm Graz, Dortmund struggled after Emre Can's red card in the 27th minute for a reckless challenge on Lee Jae-Sung. Mainz capitalised on this advantage, with Lee scoring in the 36th minute.
Shortly after Lee's goal, he fouled Serhou Guirassy in the penalty area. Guirassy converted the penalty to level the score. However, Dortmund's defence faltered again when Jonathan Burkardt scored during first-half stoppage time. Mainz continued their dominance after the break, with Paul Nebel adding a third goal in the 54th minute.

Dortmund's away form has been dismal this season, with four losses and one draw from five league games. They currently sit seventh in the standings with 16 points. Mainz trails them by three points in tenth place. The defeat highlights Dortmund's ongoing struggles away from home.
Dortmund's away performance has been concerning, having won only once across all competitions this season—a 3-0 victory over Club Brugge in the Champions League. This marks their worst away streak since the 2006-07 season. Nuri Sahin will be particularly worried about their lack of attacking threat, as they managed just two shots, with only one on target.
Mainz ended a three-match winless streak in the Bundesliga with this victory. Their recent record against Dortmund is impressive; they remain unbeaten in four encounters against them, securing two wins and two draws.
This defeat underscores Dortmund's need to address their away game issues promptly if they aim to improve their league standing. Meanwhile, Mainz can take confidence from breaking their winless run and maintaining a strong record against Dortmund.
