Bundesliga leaders Bayern Munich went down 2-1 at Mainz 05 as their unbeaten league run this season was ended after Lee Jae-sung scored either side of the break on Saturday (Dec 14). It was the first league loss for Bayern's Vincent Kompany, who last week became only the third coach in Bundesliga history not to suffer defeat in his first 13 league games in charge. Bayern, who were 5-1 winners over Shakhtar Donetsk in the Champions League earlier in the week, were missing eight injured players including top scorer Harry Kane.
Bundesliga leaders Bayern Munich suffered a first league defeat under boss Vincent Kompany as they were beaten at Mainz.
South Korea forward Lee Jae-sung took advantage of a defensive mistake to give Mainz a 41st-minute lead and added a second with a fine turn and finish on the hour mark.
Leroy Sane pulled one back three minutes before time for Bayern, who were missing several players through injury including striker Harry Kane.
"We played against a team with a lot of life and spirit and they were prepared to fight for every moment," said Kompany.
"From our side there was not a lack of fighting. We did that to the best of our ability. Today we were not at our best.
"This game, we can't play it any more. It's done. We'll use it to build a fire for next week."
Defending champions Bayer Leverkusen closed the gap to four points with a 2-0 win at Augsburg thanks to goals from Martin Terrier and Florian Wirtz.
The Bundesliga goes into a three-week winter break after next week's round of matches.
