Arsenal secured their spot in the Europa League knockout stages with a narrow, yet deserved, win over PSV on Thursday night.
Bukayo Saka and Gabriel Jesus both tested the visitor’s goalkeeper multiple times but it was Granit Xhaka - and his new-found attacking threat - was proved the difference in a 1-0 win.
Victory in the rescheduled match, postponed last month following the death of Queen Elizabeth, means Arsenal will finish in the top two in Group A having maintained their perfect start after four games.
The hosts endured a frustrating first half as they dominated proceedings, and had nine shots to PSV's one, but struggled to create clear chances and did not trouble visiting goalkeeper Walter Benitez.
Arsenal made a slow start to the second half before Bukayo Saka, Eddie Nketiah and Gabriel Jesus all came close to breaking the deadlock, with Xhaka finally giving Mikel Arteta's side a deserved lead in the 71st minute.
Substitute Martin Odegaard played the ball wide right to Takehiro Tomiyasu who found an unmarked Xhaka and the Swiss midfielder swung a half-volley past Benitez for his third goal of the season in all competitions.
Arsenal sit top of Group A with 12 points, five more than second-placed PSV, with the result putting them on the cusp of sealing top spot.
The group winners secure an automatic last-16 spot while the runners-up face one of the third-placed teams dropping down from the Champions League in a two-legged playoff tie in February.
