MF: Francis Coquelin
Wenger has put his faith in the youngster by not signing a defensive midfielder in the summer. Now he needs to repay his manager with proof that he can play at the top level in Europe.
MF: Santi Cazorla
The diminutive Spaniard is the creative hub of this team in his deeper role, and he will be important to the visitors in their bid to start with three points.
MF: Aaron Ramsey
Ramsey has yet to reach the heights of his previous two campaigns, but he will be hoping to have an influence in Europe, with his ability to drift inside and and support the lone striker.
MF: Mesut Ozil
Ozil should keep his place in the line-up, even though there may be a temptation for Wenger to be a little more cautious away from home.
