4-2-3-1: Arsenal's Strongest Possible XI vs Olympiacos

Arsenal face Olympiacos away from home tomorrow night and need a big win against the Greek side to confirm their place in the round of 16 of the UEFA Champions League.
Olympiacos defeated the Gunners 3-2 at the Emirates Stadium early on in the season and the North Londoners now need to score at least 2 away goals to qualify. In fact, any win will be enough for the British side apart from 1-0 and 2-1.
As far as the team news is concerned, it is highly unlikely that Wenger will make many changes in the starting XI that featured against Sunderland last weekend.

Expect speedy attacker Theo Walcott to return to the starting eleven and replace compatriot Alex Oxlade-Chamberlain. Other than that, Wenger will probably start the same squad as he did against the Black Cats.
Record signing Mesut Ozil has been in world class form lately and his display is surely going to be crucial. Here is Arsenal’s strongest possible starting XI vs Olympiacos.
