Borussia Dortmund had twice as many shots as 1. FC Cologne (14 shots; nine of which came after the break) and 65% of the possession, but they did not take full advantage. Here are the match facts.
Win or bust: BVB have not drawn any of their past 27 matches in the Bundesliga (19 wins, eight defeats). There has only been one longer drawless run in the history of the Bundesliga – Eintracht Frankfurt's 34-game streak between 1979 and 1980.
Assist king: Giovanni Reyna set up a goal for the fifth time this Bundesliga season; across the division, only Frankfurt's Daichi Kamada has more assists (six).
Season first: Thorgan Hazard scored his first goal of the 2020/21 season in the Bundesliga, having previously netted once in both the DFB Cup and the UEFA Champions League.
Early setback: The opener, which came in the ninth minute, was by some distance the earliest goal Borussia Dortmund have let in this season. Previously, BVB hadn't conceded a single goal in the opening half-hour of their matches.
First brace: Ellyes Skhiri netted his first brace on his 40th Bundesliga outing.
New referee: Arne Aarnink oversaw his first Bundesliga match today. The 35-year-old had actually been designated as the fourth official but stepped in after Benjamin Brand injured himself in the warm-up.
