Borussia Dortmund bounced back from a torrid seven days to get back on the winning trail with victory over Union Berlin. BVB’s title hopes took a knock with the mauling at the hands of Byern Munich last weekend, and they were stunned by RB Leipzig in the DFB Pokal in midweek. Youssoufa Moukoko climbed off the bench to score a late winner for Dortmund at Signal Iduna Park.
