Arteta was able to confirm that Riccardo Calafiori is available for the trip to Atalanta.
The defender missed out on the win over Tottenham after being forced off during Italy’s Nations League clash against France earlier this month.
Calafiori took a knock to his calf in a freak collision when he was accidentally caught down the back of his leg by France’s Ousmane Dembele.
The Arsenal summer signing received treatment on the pitch and tried to play through the problem, but eventually had to be replaced.
Calafiori is now available once again, with Arteta saying: “Riccardo was able to train today and he will be available and in the squad.
