Robert lewandowski scored an injury-time penalty for Bayern Munich to beat Wolfsburg 2-1 and move 21 points clear in the Bundesliga on Saturday.
lewandowski converted his league-leading 20th goal from the spot after Arjen Robben - who earlier missed a penalty - was pulled back by the arm by Gian-luca Itter.
It stretched Bayern's winning run to 13 games across all competitions, a personal record for Jupp Heynckes. The veteran coach has 21 victories in 22 games since returning for his fourth stint in October. Bayern hasn't lost since November.
But the side had to work hard in Wolfsburg, which took an early lead through Daniel Didavi.
"You could say we're lucky to turn the game around in the final minutes," Heynckes acknowledged. "It's very bitter for Wolfsburg because they fought brilliantly."
Some Wolfsburg fans protested against their side's lackluster season by leaving part of the stadium's north stand empty. They intended to take their seats only after 19 minutes and 45 seconds, corresponding with the year of the club's formation.
Wolfsburg didn't wait, putting Bayern under pressure from the off, and Didavi scored in the eighth minute when he beat Juan Bernat to Yunus Malli's cross and headed past his former Stuttgart teammate Sven Ulreich in Bayern's goal.
Bayern pushed for an equalizer but was frustrated by the home side's well-organized defense. Franck Ribery was fortunate to escape with just a yellow card after flinging his arm back and catching Renato Steffen in the face.
Robben had the chance from the penalty spot early in the second half, after Steffen barged Corentin Tolisso off the ball, but Koen Casteels got a hand to the Dutch winger's strike and pushed it onto the post. Sandro Wagner finally rewarded Bayern's second-half improvement with a powerful header to Robben's cross some 20 minutes in, and Robben proved influential again at the end when he earned the second penalty. Wolfsburg remained one point above the relegation zone.
Bayern next face Besiktas in the Champions league on Tuesday.
