USA striker Bobby Wood was among the scorers as Hamburg went top of the Bundesliga standings for the first time since September 2009 with a 3-1 win at Cologne, despite playing the final half-hour with ten men.
Cologne 1-3 Hamburg
Red card: Mavraj (60')
Cologne started brightly, creating chances for Yuya Osako and Leonardo Bittencourt, but Hamburg struck out of nowhere to take a surprise lead. Uncharacteristic defensive uncertainty in the Cologne rearguard played its part, with Andre Hahn slamming home after the hosts made a hash of clearing a corner. Wood doubled HSV's tally under similar circumstances, before Christian Mathenia pushed a fierce Jonas Hector strike onto the crossbar at the other end.
Cologne started the second half at full throttle as Jhon Cordoba struck the outside of a post, but their momentum was stymied by an injury to match referee Dr. Felix Brych. Replacement official Sören Storks marked his debut in the German top flight by sending off HSV's Mergim Mavraj for a second bookable offence, with Frederik Sörensen eventually reducing the arrears deep into 13 allotted minutes of added time, only for substitute Lewis Holtby to restore the visitors' two-goal lead and seal a thrilling victory moments later.
