Arsenal face CSKA Moscow on Thursday night at Ashburton Grove and will be hoping to put the tie to bed before a tough trip to Russia next week.

In front of Ospina we can assume that Wenger will pick his first-choice backline.
That means starts for Hector Bellerin, Laurent Koscielny, Shkodran Mustafi and Nacho Monreal.
The only doubt hangs over Kos, who was on the bench for the game against Stoke. Although he is managed because of his Achilles problem, it is his back that is causing problems this time.
Kos played over the international break with France, picking up his 50th cap against Russia when he played the full 90 minutes. He did not play against Colombia in France’s first game of the break, rested on the bench by Didier Deschamps who showed excellent consideration of the 32-year-old’s fitness problems.
Winning their last four games after losing the four before, Arsenal have conceded only one goal in the last 360 minutes of football. This represents a marked improvement on the rest of the season.
No player in the Arsenal squad has started more games this season than Bellerin (38).
