Dortmund make most of Bayern's slip with win over Union Berlin

Second-placed Borussia Dortmund made the most of Bayern Munich's slip against Augsburg with a 3-0 win at Union Berlin to cut their deficit to eight points, keeping alive their slim hopes of challenging Bayern this season.

Emre Can converted an early penalty, Nico Schlotterbeck headed in against his former club and Maximilian Beier scored late on as Dortmund won at Union to stay on the fringes of the title race.

"Bayern are almost unbeatable. When they make mistakes, we need to be there," Schlotterbeck told Sky Germany. "I don't want the title to be decided in March. That means we need to keep it up for as long as possible."

Arriving in the German capital after a disappointing Champions League defeat at Tottenham on Tuesday, Dortmund captain Can slotted home after Serhou Guirassy was clumsily fouled in the box with 10 minutes gone.

Just after the break, Schlotterbeck headed in a Julian Ryerson corner to double Dortmund's lead.

Not tempted to avoid celebrations against his former employers, the Germany centre-back produced his now trademark flexed bicep in front of the elated visiting fan block.

With six minutes remaining, Beier turned in a Jobe Bellingham cross to ensure victory.
