New Gunners boss Unai Emery opted to keep the £56 million signing on the bench as he preferred Pierre-Emerick Aubameyang to lead the line in a 4-2-3-1 formation for the North Londoners against defending champions Manchester City.
"Also I think he has experience and he has quality, he has the capacity like a first goalkeeper with us".
"There's a style of play around the place and comfort zone which was really hard to take for me".
"For Saturday, the decision for me is easy", Emery told the media at his Thursday press conference. Goals from Raheem Sterling and Bernardo Silva ruined Emery's welcome party as his first game as head coach ended with a loss. Emery's side travel to Stamford Bridge on Sunday for a London derby against Chelsea hoping to bounce back from their opening weekend defeat Alexandre Lacazette started on the bench against City, but former Dortmund striker Pierre-Emerick Aubameyang is confident that France global will join him in the starting line-up sooner or later.
Impressive stuff, but will it be enough for him to earn a start on Saturday?

The 20-year-old is now facing up to two months on the sidelines, but Emery has said that Stephan Lichtsteiner, who replaced Maitland-Niles against City, and fit-again Monreal are his two options for the left-back spot.
"We want a good preparation before and a good response on the pitch to that preparation". I want a consistency in our way.
"Both teams have had big changes this summer but of the two sides, Chelsea look the more settled", Keown added.
"But City made life uncomfortable for Guendouzi at times and I did not feel it was the right game to expose such a young player".
While this game does come early in the season it could give an indicator as to which club is better equipped to regain a position in the top-four.
"This week Nacho Monreal is working every day, training every day with us", Emery said.
