Leipzig win in Dortmund
Bayern suffered a jolt to their title defence, losing their first league game of the season 5-1 in Frankfurt on Saturday while RB Leipzig triumphed 3-2 at 10-men Borussia Dortmund.
In a game contested between two sides in the chasing pack, Leipzig beat Dortmund in an absorbing contest at Signal Iduna Park.
Dortmund were dealt an early blow with Mats Hummels' red card, which denied the visitors a penalty but they went on to take the lead in the 32nd minute through a Ramy Bensebaini own goal.
Ten-man Dortmund clawed their way back into the contest through Niklas Suele's close-range finish on the stroke of half-time - but Leipzig's Austrian forward Christoph Baumgartner tapped in to put Leipzig back in front early in the second half.
Yussuf Poulsen struck as the clock ticked into injury time to make it three goals and three points, keeping Leipzig fourth and opening a gap of four points to fifth-placed Dortmund, despite Niclas Fuellkrug's late header briefly giving Dortmund hope.
"These were important three points today. Very hard-earned. Really hard for the coach too. It's difficult to analyse emotionally," Marco Rose, formerly the coach of Dortmund, and now in charge of Leipzig, told 'ARD'.
