The 23-year-old suffered a knock in the win over Tottenham Hotspur, signalling to come off a few minutes from time.
Saka was able to hobble off the pitch unaided, but Arteta wasn’t able to provide an update after the game.
He told reporters, as per the Evening Standard: “I don’t know. I made two changes with the front players and suddenly he’s down.
However, the same outlet has since reported that Saka was suffering from cramp, and that he joined his teammates in training ahead of flying out to Italy.
And on Wednesday night, Arteta gave Saka the all-clear, saying he was fine and is available for the Atalanta clash.
