Leipzig loses ground after upset at Union Berlin
Second-placed RB Leipzig slipped up with a 3-1 loss at Union Berlin for its third Bundesliga defeat of the season and missed the chance to close the gap on leader Bayern Munich.
Leipzig never really found its footing in the first half and Union had the best chance on the stroke of half-time when Janik Haberer's effort with his knee sailed narrowly wide.
Oliver Burke, however, did not miss as he unleashed a left-foot shot into the top corner that left goalkeeper Peter Gulacsi frozen on the spot in the 57th to put the hosts in front.
Leipzig's Tidiam Gomis, who came on in the 59th minute, drew the visitors level a minute later, scoring with a powerful low shot.
But their joy only lasted three minutes as Union went back in front with Ilyas Ansah's close-range header.
Tim Skarke sealed the home side's win in stoppage-time to lift Union to eighth place on 18 points.
Leipzig stays on 29 points, eight behind Bayern, which can extend its advantage with a home win over bottom side Mainz on Monday (AEDT), when Borussia Dortmund, third on 28, visits Freiburg.
