BERLIN – Robert Lewandowski converted a 90th-minute penalty as runaway Bundesliga leaders Bayern Munich beat VfL Wolfsburg 2-1 on Saturday, while bottom club Cologne were denied a rare win by a video replay.

Bayern clocked up a 10th successive Bundesliga win despite falling behind to an early Daniel Didavi goal and missing a penalty, when Arjen Robben’s effort was saved by Koen Casteels just after halftime.

Sandro Wagner equalised for the Bavarians, and then Lewandowski converted their second penalty of the afternoon following a bizarre foul on Robben by teenager Gian-Luca Itter as Bayern went 21 points clear.

At the other end of the table, Cologne thought they had snatched an injury-time win over Hannover 96 when veteran Peruvian forward Claudio Pizarro scored.

But it was disallowed for offside after the referee consulted the video assistant (VAR) and the game ended 1-1, leaving Cologne three points adrift at the bottom.
