In only his second appearance in the Champions League, Yaya Sanogo scored 73 minutes into the match on a brilliant piece of skill to hand Arsenal a one-nil halftime edge over Borussia Dortmund.
It was a controversial decision by Gunners’ manager Arsene Wenger to hand the 21-year-old French forward the start but his faith was immediately rewarded when he exchanged passes with Santi Cazorla before calmly slotting past Roman Weidenfeller for his first European goal. Eight minutes later and Sanogo found himself in again, the time setting up Alex Oxlade-Chamberlain with a back-heel that the Dortmund defense managed to clear away.
With Dortmund’s traveling support 4,000 strong and in full voice, the atmosphere at the Emirates was electric as the Germans looked to capitalize on a 19th minute counter where Henrikh Mkhitaryan sought to play in Pierre-Emerick Aubameyang but Kieran Gibbs cleared away.
Two minutes later, Mkhitaryan was at it again, firing over the crossbar from just inside the area, before a minute later testing third-choice keeper Emiliano Martínez with a strike that the 22-year-old did well to save. Dortmund showed well but the edge is well in Arsenal’s favor as they ooze confidence with the ever-active Alexis Sanchez, his skillful counterpart Santi Cazorla and the pacey Oxlade-Chamberlain.
