Bayern Munich reclaimed top spot in the Bundesliga after beating Schalke as champions Borussia Dortmund suffered another defeat.
Nils Petersen and Thomas Muller scored the goals in a 2-0 victory for Bayern away to Schalke, who succumbed to their second straight defeat.
Bayern goalkeeper Manuel Neuer, making his first return to the Arena AufSchalke since his summer transfer between the two clubs, was nothing more than a spectator for 90 minutes.
Petersen gave Bayern the lead on 21 minutes and Muller made certain of the points with the second goal 15 minutes from time.
In the day's other match, Hannover struck twice in the last five minutes to record a 2-1 win over title holders Dortmund, who fell to a third defeat of the season.
Dortmund looked set for their first away win of the campaign on the back of Shinji Kagawa's well-taken 63rd-minute strike, but with four minutes to go Karim Haggui struck an equaliser and Didier Konan then kept his cool to win it in the dying seconds.
The result means Dortmund have lost three of their opening six games after waltzing to the title last season.
