With two wins from the last two matches, Arenal will be looking to make it three in a row when they visit London rivals Crystal Palace on Saturday.
Below, we look at how the team could line up at Selhurst Park.
Defence
Bernd Leno starts in goal. Ahead of him, Ainsley Maitland Niles comes in at right-back having been rested in the FA Cup win over Leeds United while Sead Kolasinac continues to play at left-back.
Meanwhile, the center back pairing should continue to be David Luiz and Sokratis largely due to the fact that no other center back is fit enough to play in the Premier League.
Midfield
Lucas Torreira did not feature against Leeds which suggests that he will without a doubt start against Palace. The Uruguayan was voted as the clubs player of the month for December and has forged a fantastic relationship with Granit Xhaka who should also start.
Ahead of the two, Mesut Ozil who has been reborn under Arteta should start in his preferred attacking midfield position.
Attack
After months struggling for form, Nicholas Pepe is finally showing glimpses of his talent and it will be no surprise to see him start yet again on the right-wing. He has two goals and one assist from his last two league starts.
Meanwhile, Alexandre Lacazette is a man out of form and needs to be rested. Pierre Emerick Aubamenyang is the better striker and will start in his natural position flanked by Gabriele Martinelli on the left-wing.
Starting XI: Leno, Niles, Kolasinac, Luiz, Sokratis, Torreira, Xhaka, Ozil, Pepe, Martinelli, Aubameyang.
