Freddie Ljungberg's men need to win to secure the top spot in Europa League Group F.
After their win against West Ham, they'll travel with a little more confidence than they have done in recent weeks, after snapping a ten-match winless streak.
Here's how we expect the Gunners to line up for the final group match test.
🔴 Predicted AFC XI vs Standard Liège
Martínez; Maitland-Niles, Chambers, Luiz, Kolasinac; Guendouzi, Willock; Saka, Smith Rowe, Nelson; Lacazette
Emiliano Martínez will continue to deputise as the cup goalkeeper. Fullbacks Hector Bellerín and Kieran Tierney both sustained injuries at West Ham, so Ainsley Maitland-Niles and Sead Kolasinac will come into the side. Granit Xhaka sustained a head injury on Monday night and won't be risked, meaning we should see a double pivot of Matteo Guendozi and Joe Willock in midfield.
A new-look attacking midfield trio comprising teenagers Bukayo Saka and Emile Smith Rowe along with Reiss Nelson, who turned 20 yesterday, should provide the ammunition for Alex Lacazette up front. The Frenchman was an unused substitute against West Ham.
Another option is to keep faith with Brazilian sensation Gabriel Martinelli, who became Arsenal's youngest-ever player to score on their first Premier League start.
