Nils Petersen and Thomas Muller scored the goals for a Bayern side who did not even need to move out of first gear to beat the Royal Blues, 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, as he had been as a young boy on the terraces of Gelsenkirchen's Park Stadion.

In the day's other match, Hannover struck twice in the last five minutes to stun reigning champions Borussia 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.
