Granit Xhaka ensured that Arsenal maintained their 100 per cent Europa League record by netting a sweet second-half strike to down PSV Eindhoven at the Emirates Stadium.
The Gunners headed into Thursday night's rearranged clash at the summit of Group A after bagging a nine-point haul in games against FK Bodo/Glimt and FC Zurich.
But they needed a moment of brilliance from Xhaka to break PSV's resistance in the 70th minute to nudge Mikel Arteta's side a step closer to the knockout stage of the competition.
