Status quo maintained in Germany
Hamburg and Bayer Leverkusen stayed in the top two spots despite being held to draws by Eintracht Frankfurt and Werder Bremen respectively.
High-flying Hamburg and Eintracht both maintained their unbeaten starts to the new term with a hard-fought 1-1 draw at the Waldstadion.
Bruno Labbadia's table-topping Hamburg went ahead in the eighth minute through a Ze Roberto header, but the hosts were on level terms after 31 minutes thanks to a Marco Russ volley.
Leverkusen, meanwhile, managed only a goalless draw at home to Werder Bremen. Stefan Kiessling was seeking to set a new league record of scoring in each of the first six Bundesliga matches, but he was denied that achievement by the offside flag early in the second half of a tight game.
Four for Freiburg
Elsewhere, bottom club Hertha Berlin's miserable start to the season continued with a 4-0 home defeat at the hands of promoted Freiburg.
