The Arsenal players celebrated in front of their fans after the full-time whistle and Arteta was asked by BBC Sport in his press conference whether he can take a positive in the manner they won the game.
“That gives you certainly momentum and confidence. Two very important things,” Arteta said.
“We can still come away and find a way to win the game. The team has to find that resilience throughout the season for 10 months, in different contexts, to be able to do that.
“Of course we have to improve a lot of things, and that will happen very soon, but in terms of managing to get that into a very positive result that is a great way to do it.”
Former Crystal Palace and Republic of Ireland striker Clinton Morrison, speaking on BBC Radio 5 Live, thinks the qualities Arsenal showed could be a sign of a season of success.
He said: “That’s the sign of champions when you don’t play well and still get the three points.
“The difference was goalkeepers. David Raya was outstanding, and Altay Bayindir made a huge mistake.
“Viktor Gyokeres fed on scraps. It is difficult for him. There’s still a lot more to come from him.”
Former Manchester United player and Sky pundit Gary Neville said “Arsenal had to change” because of the way they played in the first half.
He added: “The front three, especially the wide players, were not playing anywhere near good enough in this game.”
“Arsenal really dug in and showed a lot of resilience. Arsenal were never at their best but to come here to Old Trafford, or over to Manchester City, and get three points is big.”
