Bayern Munich were humiliated 5-2 on Saturday by Werder Bremen as the Bundesliga champions suffered one of their worst home defeats and their first competitive loss under new coach Klinsmann.

Markus Rosenberg struck twice, with Naldo, teenage sensation Mesut Ozil and Claudio Pizarro also on target for Bremen en route to a 5-0 lead against a disastrous Munich back row. Former Bremen player Tim Borowski then got the consolation goals.
Munich lost their first competitive game under new coach Juergen Klinsmann as captain Mark van Bommel lamented that "things like that can not happen." Tim Borowski spoke of a "lethargic" performance.

Werder Bremen were jubiliant.
"We are all very proud and happy to have won. We were more aggressive and made the most of our chances," said Werder Bremen's Ozil.
Nervous Bayern defense crumbles
Schalke 04 defeated 10-man Eintracht Frankfurt 1-0 to move back to the top of the standings at least until Sunday.
Schalke have 11 points, SV Hamburg take 10 into Sunday's match at VfL Wolfsburg, Bayer Leverkusen have nine points, with Bremen, Munich, Hertha Berlin and Borussia Dortmund on eight points each.
Judging by the season so far, the unbeaten champions Munich were favoured over the runner-ups Bremen, especially looking at the midweek Champions League results with Munich winning 1-0 at Steaua Bucharest while Bremen were held 0-0 by Famagusta.
But Bremen dominated from the outset against a nervous Munich defense and were awarded for their courage with a big win.
Rosenberg broke the deadlock after half an hour, taking up a defense-splitting pass from Ozil and slotting a low shot past Michael Rensing.
Bremen doubled the lead on the stroke of halftime when Naldo tapped home after Ozil's freekick and Ozil ended any Munich comeback hopes when he fired high into the net nine minutes into the second half.

Pizarro and Rosenberg again, after Rensing missed a free kick, made it 5-0 as memories returned of Munich's biggest Bundesliga home loss, 7-0 against Schalke in October 1976.
Borowski spared Munich from total disaster with his late goals, but admitted swiftly afterwards: "This was a disastrous showing, we must apologize to the fans."
Hertha, Schalke notch wins
Schalke were in full command against lowly Frankfurt but did not break the deadlock until Chris was sent off in the 34th for elbowing Heiko Westermann. Newly-hired Jefferson Farfan got the winner seven minutes later but Schalke failed to impress.
Elsewhere, Hertha Berlin won 1-0 at Borussia Moenchengladbach from Gojko Kacar's first half strike, with the home side's Oliver Neuville denied by the post twice. Arminia Bielefeld defeated Cologne 2-0.
Energie Cottbus got the first goal of the season, from Dennis Sorensen, but were held 1-1 by VfL Bochum to remain at the bottom of the table.
A hat-trick from Patrick Helmes helped Leverkusen to a 4-0 win over Hanover 96 on Friday, while the other Sunday games are VfB Stuttgart vs SC Karlsruhe and Hoffenheim vs Dortmund.
