Arsenal take on Olympiacos in the first leg of the Europa League round of 16 tonight.
The Greek outfit shocked the Gunners last term as they eliminated them in the last 32 of the competition.
The north London giants will be aiming to avenge the result with a strong performance in Piraeus.
Kieran Tierney is an automatic choice on the left side of the defence.
Partey has lacked consistency amid regular injuries and he misplaced several passes in the recent 1-1 draw at Burnley.
Xhaka made a horrendous blunder which led to the Clarets equalising and he will be eager to redeem himself.
In the attack, there may be a solitary change with Willian making way.
Emile Smith Rowe may be available after a hip problem, but he may start the game on the substitutes’ bench.
Predicted Arsenal lineup (4-2-3-1): Leno; Bellerin, Luiz, Gabriel, Tierney; Partey, Xhaka; Saka, Odegaard, Aubameyang; Lacazette.
