Arsenal were shocked in midweek by Anderlecht as they dropped two crucial points in their champions league group while leading 3-0 against the Belgians.
The result might not influence their qualification to next round but will prove pivotal in deciding the team who will top the group. Dortmund remain clear favorites.
Gunners will have to make sure no such blunders are repeated in the premier league when they face Swansea on Sunday.
Swans are only two points behind gunners and a win can take them above the North London side.
With Arteta out injured expect Flamini to return to starting XI.
Wilshere will be available for selection as well recovering from Illness but it is likely that he may start from the bench.
Will underfire Monreal be benched to start Chambers as central defense partner of Mertesacker and Bellerin as RB, we shall see. Chambers has been brilliant lately in the full back role.
Here is Arsenal’s probable 4-2-3-1 formation vs Swansea.
