Guimaraes, Portugal, Nov 6, 2019 (AFP) - Arsenal's faltering form continued as a much-changed side limped towards the last 32 of the Europa League with a 1-1 draw at Vitoria Guimaraes on Wednesday.
Shkodran Mustafi's header 10 minutes from time looked set to hand the Gunners a barely deserved three points and maintain their 100 percent record in Group F.
However, Vitoria secured their first point in the group thanks to Bruno Duarte's acrobatic stoppage-time equaliser.
Arsenal remain well placed to reach the knockout stages as they top the group with 10 points from their first four games.
However, another underwhelming performance and result will do little to ease the mounting pressure on manager Unai Emery.
The Spaniard has been heavily criticised for a run of two wins in nine Premier League games, leaving them six points outside the top four, and Emery prioritised Saturday's vital trip to Leicester with his starting line-up.
Pierre-Emerick Aubameyang was named as Arsenal's new captain on Tuesday after Granit Xhaka was stripped of that responsibility for his angry outburst towards the club's fans when being substituted against Crystal Palace 10 days ago.
However, Aubameyang was not even included on the substitutes bench as Emery made eight changes from the side that started Saturday's 1-1 draw at home to Wolves.
Vitoria came closest to scoring in the first half when Nicolas Pepe smashed a long-range shot off the underside of the bar.
Arsenal had barely created anything of note but seemed set to get out of jail when Mustafi nodded home Pepe's free-kick to give the visitors the lead.
But going behind summoned a response from the hosts who threw caution to the wind in the closing stages and were rewarded in the first minute of injury time.
Former Tottenham winger Marcus Edwards was the creator as Arsenal failed to clear his cross before Duarte hooked home the loose ball with a bicycle kick.
