The Sweden striker scored twice in the 4-1 win.
Arteta said afterwards, “I think it’s probably the best game that he (Gyokeres) has played for us.
"The most complete of the two goals by his overall performance, I think, was incredible, and Ebs (Eze) as well. I mean, now he has another incredible experience playing against them, and I'm very happy because he deserved it.”
Arteta also had a word for Bukayo Saka, adding: "I loved his attitude, his presence, how dominant he was in the game from the beginning.
"The first reaction immediately, he wants to grab the game, and he really wants to say, I'm here. And that's what I love, he didn't score, but he was in every action. I think he was really, really good."
