Borussia Dortmund's Pierre-Emerick Aubameyang celebrated scoring in the Ruhr derby against Schalke by producing a mask. Aubameyang pounced for his 24th Bundesliga goal of the season after ex-Manchester United midfielder Shinji Kagawa had burst forward. Dortmund were denied a second goal when teenage forward Ousmane Dembele hit the post. Schalke equalised after Thilo Kehrer finished into the bottom left corner.

Dortmund are fourth in the table, 16 points behind leaders Bayern Munich who thrashed Augsburg 6-0. Schalke remain in mid-table. Elsewhere, second-placed RB Leipzig hammered bottom club Darmstadt 4-0. Naby Keita scored twice while Sweden international Emil Forsberg and Willi Orban also found the net. Darmstadt collapsed following the sending-off of Sandro Sirigu in the 72nd minute. Denmark midfielder Thomas Delaney scored a hat-trick as Werder Bremen won 5-2 at Freiburg, while Hamburg beat Cologne 2-1.
