Yaya Sanogo opened the scoring inside two minutes to set the Gunners on their way, before Alexis Sanchez added a second with a beautiful shot that curled past Roman Weidenfeller.

Dortmund did have chances, however, and had third-choice goalkeeper Emiliano Martinez to thank for keeping them in the lead. The Argentine produced a fantastic save to deny Henrikh Mkhitaryan at the end of the first-half to keep the game at 1-0 and did everything that was asked of him.

Defensively, the Gunners looked more solid than they had done in recent weeks, keeping a clean sheet.

Mikel Arteta and Aaron Ramsey disappointed, but Alex Oxlade-Chamberlain, on his 100th appearance for Arsenal, was an impressive performer down the right.

Arsene Wenger may have raised a few eyebrows when he opted to start Sanogo over Joel Campbell and Lukas Podolski, who were both on the bench, but his gamble certainly paid off.
