Arsenal are drawing 1-1 with Borussia Dortmund at half time in their Champions League Group F clash at the Emirates Stadium.
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.
