Tomas Rosicky, who returned to training on Monday after being out will illness, is also left out.
Speaking to Arsenal.com, Arsene Wenger said
“Gabriel travelled and is available. Chamberlain did not travel, Rosicky did not travel, he comes back from sickness.
“Gabriel replaces Apkom in the squad which was involved on Saturday against West Ham.”
Gabriel returned to training on Monday along with Mikel Arteta and Mathieu Debuchy who trained separately from the first team.
Arsenal face an uphill battle to qualify for the quarter finals of the competition as you already know but the belief amongst the players and fans is high even though the side will have to make history if they are to seal qualification.
No other side has ever overturned a 3-1 defeat from the first leg in the knockout stages of the completion.
Arsenal certainly like to keep things interesting.
