Predicted Arsenal lineup (4-2-3-1) vs Olympiacos, Ceballos and Xhaka start
Arsenal will make the trip to Athens to face Olympiacos in the first leg of their Europa League round of 32 tie.
The north London side recently ended a four-match winless run in the top-flight with a 4-0 triumph over Newcastle United and manager Mikel Arteta will be hoping to build momentum with another victory.
Emiliano Martinez has been the preferred goalkeeper for the Cup competitions and he is expected to replace Bernd Leno between the sticks.
The defence may witness a few changes. Sokratis may come in for Shkodran Mustafi, due to the familiarity with the atmosphere in his home country.
At left-back, Bukayo Saka may be rested. Sead Kolasinac should make his comeback after more than a month on the sidelines with a thigh injury.
Granit Xhaka and Daniel Ceballos impressed as a pair against the Magpies and they are likely to keep their spots with Lucas Torreira out with an illness.
In the attack, a change is expected in the number 10 spot. Mesut Ozil is unavailable due to personal reasons and he may be replaced with Joe Willock.
Alexandre Lacazette should reclaim the striker role ahead of Eddie Nketiah. Pierre-Emerick Aubameyang and Nicolas Pepe will definitely retain their positions.
