Werder demolition job in Munich 
Bremen issued the clearest possible signal of their title ambitions with this walloping of champions Bayern München on their own turf.
There was not much to cheer for Bayern as the Munich's famous Oktoberfest got underway, as a rampant Bremen side took them apart, winning 5-2 (2-0) after at one point leading 5-0. It was the biggest home defeat for FCB since losing 4-0 to Arminia Bielfeld back in March 1979.
Markus Rosenberg (30./67.), Naldo (45.), Mesut Özil (54.) and Claudio Pizarro (59.) fired Bremen onto easy street before former Werder man Tim Borowski got a late brace (71. /85.) for the outclassed home side.
Bremen on fire
Werder went on the offensvie from the start in front of a 69,000 crowd in the Allianz Arena against an out-of-sorts Bayern and could have taken the lead on 18 minutes, Pizarro lobbing narrowly wide.
They deservedly went in front on the half-hour mark, Mesut Ösil brilliantly splitting the home defence for Rosenberg to slot the ball past FCB keeper Michael Rensing. Minutes later it was 2-0, when Rensing pushed Özil's free-kick onto the feet of Naldo, who just had to knock the ball over the line.
Klinsmann rings changes
Bayern coach Jürgen Klinsmann brought on Borowski and Massimo Oddo at half time, but it just went from bad to worse for the home side. Diego put in Özil for number three, and Rosenberg set up Pizarro to make it 4-0. And it was not over yet. Rensing, having a truly bad day, dropped a Diego cross, leaving Rosenberg with the easiest of chances to make it five.
Bayern's two late strikes saved them from complete humiliation, but it still left them on the wrong end of a home defeat unparallelled in recent times.
