The 26-year-old joined the Gunners from Bayer Leverkusen in the summer but had to wait for Thursday night's 4-2 Europa League win over Vorskla Poltava to make his bow.
But the visiting side from Ukraine pulled two late goals back to leave Emery's team without a single clean sheet this season.

The two Vorskla goals - the second of which came with the last kick of the game - spoiled an otherwise confident debut by goalkeeper Bernd Leno, who was rarely troubled in the opening 60 minutes and showed good composure when playing the ball out from the back. We need players and need to give minutes to players.
I think it's unlikely he'll start against Everton after picking up this knock but Torreira will hopefully be fit enough to line-up against Brentford in the League Cup next Wednesday. It can't be a coincidence that we were cruising at 3-0 when he left the field last night before conceding two late goals to see the match end 4-2. "Each minute he is playing, he is doing very well". He didn't say the league is Petr's competition and the Europa League is mine.
"For him, it takes minutes for the game and confidence for continuing also because he will be continuing to play matches in the next week".
However, Emery has played down those fears after telling reporters after the game that he hopes Torreira will be available for selection for the visit of Everton to the Emirates on Sunday afternoon.
