Bayern maintain perfect record
Bayern Munich kept pace with Borussia Dortmund at the top of the Bundesliga with Franck Ribery and Arjen Robben both on target in a 2-0 win over Nurnberg.
Nurnberg went closest to breaking the deadlock as Bayern struggled to get their game going in the first half, though David Alaba missed a penalty for the hosts.
When Pep Guardiola's side found top gear in the second half, though, there was only one side who was going to win with wingers Ribery and Robben clinching their third straight win.
Sidney Sam was on target twice for Bayer Leverkusen as they moved into a four-way tie for top spot with a 4-2 win over Borussia Monchengladbach.
Stefan Kiessling scored first before setting up Sam to give Leverkusen a two-goal lead at the interval.
Martin Stranzl and Juan Arango brought Gladbach back on terms, but Sam's second and a Gonzalo Castro goal ensured Sami Hyypia's men extended their perfect start to the season.
Mainz also maintained their perfect start to the campaign with a 2-0 win at home to Wolfsburg, who ended the match short-handed after Luis Gustavo was sent off in the second half.
Eric Maxim Choupo-Moting had opened the scoring four minutes earlier, and Nicolai Muller put away Mainz's third straight victory with a goal in the 78th minute.
Schalke's poor season start continued with a 2-1 loss at Hannover, where the visitors finished with nine players and the hosts 10.
Schalke captain Benedikt Howedes was sent off inside 15 minutes for a foul on Mame Diouf.
Szabolcs Huszti scored from the spot, and the Hungarian crossed for Diouf to score with a header in the 42nd. Adam Szalai pulled a consolation goal back in the 55th minute.
Huszti was sent off for a raised foot in the 74th, and Schalke defender Christian Fuchs earned his second yellow in the 85th.
There were six goals and three red cards as Hoffenheim and Freiburg had to settle for a point each in a 3-3 draw at the Rhein-Neckar-Arena.
Sejad Salihovic was Hoffenheim's hero and villain in a matter of seconds as he put the hosts ahead but then received his marching orders in the tenth minute.
Oliver Sorg levelled for Freiburg before Kevin Volland restored Hoffenheim's advantage, which again lasted only a few minutes before Karim Guede brought Freiburg back on terms.
The visitors lost Francis Coquelin to a red card before the interval, yet they took the lead for the first time through Sebastian Freis in the 65th minute. Tobias Strobl levelled in the 77th minute before the final red card of the game was shown to substitute Admir Mehmedi in stoppage time.
Adrian Ramos scored in the 74th minute to lift Hertha Berlin to a 1-0 home win to Hamburg in Saturday's late game.
Ramos tapped home from close range after good work down the left flank by Anis Ben-Hatira and Nico Schulz.
Hertha defender John Anthony Brooks left the game with tightness in his thigh in the 23rd minute. Brooks earned his first cap with the United States national team in a friendly against Bosnia-Herzegovina this month.
