Borussia Dortmund had more shots (14-11) and more of the ball (57%) in a comfortable 5-1 "Westderby" win. Erling Haaland set a Bundesliga record. The match facts...
Early lead: Borussia Dortmund took a first-minute lead for the first time in almost seven years. By the time Raphael Guerreiro scored after 52 seconds, not a single Cologne player had touched the ball. It was the fourth-quickest goal of the season; the fastest was scored by Augsburg's Marco Richter in a 2-2 draw with Bayern on Matchday 8. The last Bundesliga goal BVB scored in the first minute was in a 2-0 victory over Mainz 05 on 20 April 2013. Marco Reus was the scorer.
Goal frenzy: Only one club has previously reached 10 goals in their first two Bundesliga games after the winter break: Borussia Mönchengladbach in the 1966/67 season (11).
There's quick, then there's Haaland: Erling Haaland became the first player in Bundesliga history to score five goals in his first two matches. He took only 56 minutes to reach that tally – also a record. The record for fastest five goals was previously held by Paco Alcácer (72 minutes). For the first time the 19-year-old missed a shot, scoring "only" two goals from his three shots. He had converted all three shots on his debut in Augsburg.
When Sancho scores...: Jadon Sancho scored the third goal shortly after the break to all-but seal the win. Borussia have never lost when the Englishman has scored (W16 D5). He was involved in eight of Dortmund's 13 shots before coming off (three taken himself, five teed up).
...and he does score...: Jadon Sancho has scored eight goals in his last eight Bundesliga games and set up the opener too. It was his 12th assist of the season, which puts him joint-top of the ranking alongside Bayern's Thomas Müller.
Provider: As he did in Augsburg, Mats Hummels set up a goal with an outstanding pass. It was his fourth assist of the season – more than he has ever managed and a new personal best for a campaign.
Home fortress: Borussia Dortmund remain the only Bundesliga team yet to have lost a home game this season. They have taken 21 out of a possible 27 points on home turf.
That Friday floodlight feeling: The Black & Yellows have not lost any of their last 28 home games on a Friday evening (W20 D8). Their last home defeat on a Friday night dates back to January 2004.
Empty-handed: 1. FC Cologne have not won any of their 20 league games in Dortmund over the last 29 years (D4 L16).
