Jamie Carragher has highlighted the fixtures he feels will dictate whether or not Unai Emery remains at Arsenal.
The Gunners endured a seesaw evening on Thursday when they came from behind to beat Vitoria 3-2 in the Europa League.
Gabriel Martinelli pulled Arsenal back into the contest after the Portuguese side hit the front thanks to a goal from former Tottenham man Marcus Edwards, before Bruno Duarte put the visitors back in front.
Then Nicolas Pepe provided two sumptuous free-kick goals late on to turn the tide in Arsenal's favour.
But despite the impressive comeback, Arsenal's flaws particularly at the back were there to see again and have led to plenty of criticism.
Former Liverpool great Carragher is one of the many pundits unsure about Emery's role at the Emirates and he has questioned how much progression there has been since Arsene Wenger left last year.
"No-one was demanding a radical culture shift with Arsenal abandoning Wenger’s attacking beliefs, but we certainly hoped for more than witnessed so far," Carragher told The Telegraph.
"What are Arsenal supposed to be? A more consistent version of Wenger’s side? Are they a pressing or counter-attacking team?
"Now the club is entering another key period, after which it will become clearer if Emery is capable of changing perceptions of this Arsenal team.
"Between December 15 and New Year’s Day, Arsenal face Manchester City, Chelsea and Manchester United. They also travel to Everton. There will be no patience for repeated lacklustre away days."
