Bayern Munich fell to a shock Bundesliga defeat on Saturday afternoon as they were beaten 2-1 by relegation-threatened Augsburg. Hiroki Ito had headed the German giants into a first-half lead, but Bayern were sloppy throughout the contest and fell behind after goals from Arthur Chaves and Han-Noah Massengo. Vincent Kompany's side could now see their lead at the top of table cut down if nearest challengers Borussia Dortmund beat Union Berlin.Bayern have already stormed into what may be considered by some an unassailable lead at the top of the Bundesliga but had the chance to increase it further when Augsburg visited on Saturday.It was the minnows who had the first good chance of the game, however, as the lively Alexis Claude-Maurice struck from distance but couldn't manage to find the target.Bayern still had most of the ball, boasting over 80% of possession during the first 15 minutes, but Kompany's side failed to do much with it until getting the opener midway through the first half. Michael Olise conjured up his 15th league assist of the season, crossing for Ito to head in from a corner.The reigning German champions smelled blood in the water and almost got a second goal soon after, but Lennart Karl's streching volley drifted wide after good work from Luis Diaz.Augsburg kept themselves in the game, not allowing Bayern to overwhelm them, and nearly got an equaliser just before half-time when Robin Fellhauer smashed the bar.Bayern failed to raise their level in the second half, being too pedestrian in possession, and were made to pay for it when Augsburg grabbed a deserved leveller. Mert Komur's tantalising delivery from a corner was met by Chaves, who buried his header to make it 1-1.The script was well and truly ripped up when the visitors took a shock lead inside the final ten minutes. Dimitris Giannoulis found space down the left wing and found the free Massengo in the box, the 24-year-old converting calmly from a central position.Bayern applied some pressure in the final exchanges but couldn't carve out the quality chances needed to get themselves level, with Olise hitting the bar with the final kick of the game, and ended up losing for just the second time in the Bundesliga so far this season.He didn't get on the scoresheet, but it was Alexis Claude-Maurice who stoked some fear into the Bayern team with his fearless dribbling, often leaving defenders strewn around him as he charged forward. The Bundesliga champions had no real answer to his performance.It's been a season where pretty much everything has gone right for Harry Kane, but on Saturday he cut a frustrated figure. The England captain failed to get himself into the game like he usually does, with his trademark passing notably absent. There are all sorts of records left for him to chase in the remainder of the campaign, but he didn't make a dent in any of those pursuits here.Add GOAL.com as a preferred source on Google to see more of our reporting
