Borussia Dortmund remained at the top of the Bundesliga with a big win over struggling Freiburg, but Bayern Munich trail on goal difference alone after their victory over Wolfsburg.
Robert Lewandowski dispelled any doubts over his commitment to the Borussia Dortmund cause this season with two goals in a 5-0 Bundesliga win over Freiburg.
Lewandowski has been involved in controversy this week, but he was named in Dortmund's starting line-up on Saturday and struck twice in the second half. The visitors already led 2-0 through Marco Reus' brace, the second a penalty after Fallou Diagne was sent off for fouling Lewandowski, and substitute Jakub Blaszczykowski completed a thoroughly one-sided win.
Dortmund remain level on points with Bayern Munich at the summit after the reigning champions beat Wolfsburg 1-0.
Thomas Muller struck the only goal from a narrow angle in the 63rd minute and Bayern, like their rivals, moved to 19 points from seven games in an unbeaten start.
Just one point behind are Bayer Leverkusen, who extended their best-ever start to a Bundesliga season with a 2-0 win over Hannover at the BayArena.
Simon Rolfes and Sidney Sam scored first-half goals as Leverkusen warmed up for their midweek Champions League tie with Real Sociedad with their sixth win in seven league matches this season.
The win also gives Sami Hyypia's men a six-point cushion over Hannover, who remain in fourth place despite losing their third way game of the season.
Hoffenheim and Schalke shared six goals in a dramatic 3-3 draw at the Rhein-Neckar Arena.
Kevin-Prince Boateng and Joel Matip got Schalke off to a flying start, but Anthony Modeste hauled Hoffenheim back into the game. Marco Hoger restored Schalke's two-goal advantage before half-time, but a Roberto Firmino penalty and a David Abraham free-kick earned Hoffenheim a share of the spoils.
Hertha Berlin came from behind to beat Mainz 3-1 at the Olympiastadion and move up to fifth in the table.
Nicolai Muller gave Mainz a seventh-minute lead, but their former striker Sami Allagui came back to haunt them with two goals to turn the game on its head. Anis Ben-Hatira then completed the win for Berlin, who bounced back from a rare home defeat to Stuttgart to turn their home into a fortress again.
