Milivoje Novakovic scored twice as Cologne came from two goals down to beat Bayern Munich 3-2 at home in the Bundesliga yesterday.

The Slovenian striker equalised in the 63rd minute and scored the winner in the 73rd, to cancel out first half goals from Hamit Altintop and Mario Gomez for Bayern. Christian Clemens got Cologne's revival under way in the 55th.

Bayern drops to fifth, 15 points behind leader Borussia Dortmund, overtaken by Mainz and Hannover in 3rd and 4th respectively. Cologne remains 16th.

Bayer Leverkusen lost 1-0 at Nuremberg but remains second, 12 points adrift of Dortmund.

Claudio Pizarro scored an injury time goal for Werder Bremen to earn a 1-1 draw at Mainz, while there were home wins for Hannover and Hoffenheim over Wolfsburg and Kaiserslautern respectively.

Bayern should have been reduced to 10 men in the 19th minute, when Holger Badstuber, the last defender, cynically brought down Novakovic when the striker was through on goal.

The Bundesliga's youngest referee, Felix Zwayer, showed Badstuber a yellow card

Gomez scored his 16th of the season when he deflected a cross from Thomas Mueller past former teammate Michael Rensing. The Cologne goalkeeper was unlucky to see the shot deflect in between his legs.

Bayern – playing without Arjen Robben due to a cold – had full control of the game, and it was just a matter of time before the second arrived.

It came in the 43rd when Hamit Altintop blasted the ball past Rensing into the far corner from a tight angle.

Clemens scored when he ran onto a through ball from Christian Eichner and rounded goalkeeper Thomas Kraft to finish from a tight angle.

Novakovic's equaliser prompted Bayern coach Luis van Gaal to bring on Franck Ribery for his first Bundesliga action since 15 January.

But Novakovic scored again when he held off the challenge of Badstuber and blasted it past Kraft to leave the goalkeeper shaking his head.

Clemens should have added another for Cologne late on, but he blasted the effort over.

In the Lower Saxony derby, Steve McClaren's new-look Wolfsburg side had a bad start at Hannover when Sergio Pinto scored in the fourth minute. The midfielder let fly from 23 metres (yards) and Diego Benaglio somehow let it slip under his arms.

Diego crashed a penalty off the crossbar in the 80th, after he was brought down in the area by Emanuel Pogatetz. It was Wolfsburg's third penalty miss in a row, and Hannover held on to win 1-0.

Werder Bremen's Claudio Pizarro scored in the third minute of injury time, when he turned smartly in the area to volley past Mainz keeper Heinz Mueller.

Andre Schuerrle scored for Mainz in the 19th, and dedicated the goal to teammate Adam Szalai, ruled out for the rest of the season because of a right knee injury.

Christian Eigler scored the winner for Nuremberg over Bayer Leverkusen, before he was sent off late on for a second yellow card.

Gylfi-Thor Sigurdsson and Sebastian Rudy gave Hoffenheim a 2-0 halftime lead over Kaiserslautern, but the visitors equalised with two goals in as many minutes from Erwin Hoffer and Brazilian defender Rodnei in the 58th and 60th.

Vedad Ibisevic scored the winner for Hoffenheim in the 62nd to make it 3-2.
