Arsene Wenger was full of praise for his side following their comprehensive 4-1 victory over Hull City on Saturday.
Alexis Sanchez (17, 83), Theo Walcott (55), and Granit Xhaka (90 2) were all on target as the Gunners put on a dominant display at the KCOM Stadium.
Speaking after the game, Wenger praised the "vision" of Alex Iwobi, who had played provider for the first two goals.
"I started him last year because I've seen that there's something in him that is quality of vision, quality of give and go, of movement," Wenger told the club's official website.
"He can break the lines with a pass and individually as well, so there's a lot in the locker.
"Overall, he's only 20 years old so you could see that he has gained in confidence now. He can take people on much more and he has gained power as well. It's interesting what he has done."

Wenger also heaped praise on Walcott for his mature performance, saying that the English winger is "getting slowly there".
"He is not completely ready physically but today I felt in the second half he was much better than the first," Wenger said. "He has interesting qualities for us.
"He goes behind, many players like to come to the ball and he's one of the players who is very dangerous for the quality of his runs and his receptions. I think today in the first half he was influential on the ball. He scored one as well, so he's efficient and that's what you want."
The Arsenal boss added that he has the utmost faith in the England man "because I look at the overall balance of the team".
"As I told you, we need players who go behind the defenders and he can do that well," Wenger added. "When Sanchez plays up front, he likes to come to the ball. To have someone who goes behind at the same moment helps us to have many options."
