The Gunners travel to Belgium this Wednesday to improve on what has been a tough Champions League journey so far in their first game against Anderlecht.
Arsenal aren't in the best of form due to injuries and the past few weeks have seen the team struggle to retain any consistent winning form. They are buoyed by the news that Walcott is fit and available as well as Ramsey and Wilshere, who have both recovered from slight knocks. Chambers is available to step into defence, which should also strengthen the team up a bit more as Koscielny is still doubtful.
Emiliano Martinez is also due to make his European debut in goal tonight after David Ospina was ruled out with a thigh injury.
Anderlecht are without N'Sakala due to a knee injury but they have Anthony Vanden Borre returning to action after tearing his calf muscle.
The Belgian team are on the bounce back from two domestic losses in a row and will be looking to improve their Champions League form as much as Arsenal.
This could be a tough game for both teams but Arsenal should be able to bag a win, however, nothing is predictable with the Gunners despite being the favourites to win this game.
Predicted line-ups:
Arsenal - Martinez, Monreal, Chambers, Mertesacker, Gibbs, Arteta, Ramsey, Wilshere, Sanchez, Cazorla, Welbeck
Anderlecht - Proto, Vanden Borre, Mbemba, Heylen, Deschacht; Defour, Tielemans; Najar, Praet, Suarez; Mitrovic
Prediction: Anderlecht 1-2 Arsenal
