Bayern humbled by Hertha Berlin
Niko Kovac suffered his first defeat as Bayern Munich boss as the Bundesliga champions slipped to a concerning 2-0 loss away at Hertha Berlin on Saturday (AEST).
Held to a 1-1 home draw by Augsburg in midweek, the return of Robert Lewandowski, James Rodriguez and a raft of regulars failed to prevent Bayern from dropping points for a second successive outing.
Bayern was disjointed in defence and uncharacteristically wasteful in attack as Vedad Ibisevic's 23rd-minute penalty and a shot from Ondrej Duda on the stroke of half-time gave the home side its first victory against the Bavarian giant in 15 league meetings.
It added up to a forgettable homecoming for former Hertha player Kovac, who will expect a response to this mini slump when Bayern host Ajax in the UEFA Champions League.
Recalled as one of seven changes, Jerome Boateng's first major act was to nod a James corner agonisingly wide of the top corner.
His next, however, was a panicked challenge on Salomon Kalou that allowed Ibisevic to convert the opener, leaving Bayern rattled.
Arjen Robben inexplicably turned David Alaba's low cross over the bar at point-blank range and the miss was punished a minute before the break, Duda emphatically meeting Valentino Lazaro's clever cut-back.
Boateng went close to reducing the deficit with another fine header beyond the hour but Thomas Kraft, deputising for the injured Rune Jarstein, reacted well to deny the Germany international.
Kovac threw on Thomas Muller, Serge Gnabry and Sandro Wagner in an ultimately fruitless search for a way back into his most alarming match in charge.
