Good match done by Klopp's boys with Mkhitaryan scoring in 13th minute after a race in the right side, a run parallel with the goal and a well placed long shot giving Green no chance to keep it.
Soon after Dortmund's opener, Dieter Hecking's boys had several chances to make it 1-1, but they couldn't take them.
After several ocassions from Jojic and Reus, Lewandowski makes it 2-0, dodging the defenders and placing a shot in the left-top corner, after Reus provided him a short pass.
Good performance from Dortmund on Signal Iduna Park (Westfallen stadion)
