Robert Lewandowski struck a last-minute winner for Bayern Munich to come from behind and beat Hoffenheim 2-1 in the Bundesliga on Saturday.

Hoffenheim forward Kevin Volland scored after nine seconds, capitalizing on a poor back pass from David Alaba and shooting through Manuel Neuer's legs to match the fastest German league goal ever scored. Karim Bellarabi of Bayer Leverkusen managed the same feat one day short of a year ago against Borussia Dortmund.

Douglas Costa, Arjen Robben and Thomas Mueller all went close as Bayern sought a response. The latter forced a great save from Oliver Baumann, then struck the right post, before finally equalizing on the rebound with his right thigh in the 41st after Baumann saved Costa's initial effort.

Costa was causing havoc on the left wing and another new signing, Arturo Vidal, struck the crossbar in the 66th, before Pep Guardiola brought on Lewandowski.

But Bayern was down to 10 men shortly afterward as Jerome Boateng was sent off and gave away a penalty for blocking a free kick with his arm in the 73rd. The defender earned his first yellow card for a foul two minutes earlier.

But Eugen Polanski struck the penalty against the post, prompting a final push from Bayern.

Lewandowski was denied by Baumann, Mueller hit the post again, before Costa, now on the right wing, beat two defenders and cut the ball back for Lewandowski to convert inside the left post.

Wolfsburg could only draw 1-1 at Cologne amid speculation Kevin de Bruyne was playing his last game for the club.

Simon Zoller scored for Cologne in the 30th but missed further chances for the home side. Wolfsburg substitute Niklas Bendtner equalized in the 83rd.

De Bruyne, linked with a possible transfer to Premier League side Man City, endured a second successive frustrating game and was denied a winning goal in injury time when Timo Horn saved his first effort and Matthias Lehmann blocked his follow up on the line.

Promoted Darmstadt held Schalke to a 1-1 draw in Gelsenkirchen, with Konstantin Rausch scoring for Darmstadt in the ninth, only for the visitors to be denied by Julian Draxler's equalizer two minutes after the break.

A perfectly struck 17th-minute free kick from specialist Hakan Calhanoglu was enough for Bayer Leverkusen to win 1-0 at Hannover.

Marco Russ scored late to salvage a 1-1 draw for Eintracht Frankfurt at home against Augsburg, cancelling out Brazilian forward Caiuby's 23rd-minute strike.

Hamburger SV and Stuttgart were targeting their first points in the late game.
