Gunners will bounce back, insists Wilshere

Ciro Immobile and Pierre-Emerick Aubameyang struck in a 2-0 midweek victory for the Bundesliga club, but the winning margin should have been a landslide after the Gunners were overwhelmed at Signal Iduna Park.
It was clearly their toughest fixture in Group D but the dismal performance has raised concerns over their ability to make any meaningful impact in Europe. Adding to the despondency is the ankle injury that forced Wilshere off in the closing stages.
