Two goals each from Maximilian Philipp and Pierre-Emerick Aubameyang ensured Borussia Dortmund went to the top of the Bundesliga table as they beat Cologne 5-0.
Philipp flashed a header from Andriy Yarmolenko into the Cologne net before Sokratis Papastathopoulos made it 2-0, with the help of the Video Assistant Referee, after he had initially been adjudged to have pushed Timo Horn before poking in to the net when the goalkeeper dropped the ball.
Aubameyang then scored twice in a minute, the first from the penalty spot, before Philipp added a fifth as Dortmund moved on to 10 points from their four fixtures so far, with Cologne remaining pointless having scored just one goal.
Hoffenheim, one of the other two unbeaten clubs, missed the chance to move on to 10 points themselves as they were held to a 1-1 draw by Hertha Berlin.
Sandro Wagner’s sixth-minute header from Andrej Kramaric’s cross put Hoffenheim on course for their third successive home win. However, Alexander Esswein equalised for the capital club 10 minutes into the second half.
Bayer Leverkusen picked up their first win of the season and left Freiburg still searching for theirs, with a 4-0 victory at the BayArena.
Kevin Volland opened the scoring in the 21st minute, Charles Aranguiz doubled the lead seven minutes later, then Volland tapped in his second 11 minutes before half-time.
Aranguiz then set up Julian Brandt for a fourth goal with four minutes remaining, as Leverkusen moved up to 12th in the table and left Freiburg in the bottom three.
