Borussia Dortmund have defeated Arsenal 2-1 at the Emirates Stadium in the Champions League Group F.
The German giants had two early half-chances through Mats Hummels and Marco Reus, but both were long-range efforts that did not trouble Wojciech Szczesny.
However, Dortmund surged ahead in the 16th minute through Henrik Mkhitaryan. Mikel Arteta and Aaron Ramsey failed to clear the ball and it fell to Robert Lewandowski, who passed it to the Armenian midfielder to slot home with ease.
Arsenal pressed on for the equaliser and restored parity through Olivier Giroud four minutes from half time.
Ramsey released Bacary Sagna on the right and the full-back's cross was turned in by the French striker.
Arsene Wenger's Arsenal side dominated proceedings for most of the second half with substitute Santi Cazorla running the show at the Emirates.
The Spanish midfielder himself went close to making it 2-1 to the London club midway through the half when his long-range effort clipped the frame of the Dortmund goal.
Arsenal pressed on for the winner but it was Dortmund who won the contest, with Lewandowski volleying home a Kevin Grosskreutz cross in the 82nd minute.
