Arteta was appointed director of Arsenal in December, but had a mixed few months in his first leadership role.
However, the victory against the Wolves was the fourth in a row in Arsenal in all competitions.
And speaking of the game of the day, Keown can only see good signs for the future.
“They seem much more resolute,” he said.
“I am immensely impressed with Arteta, I think it is the first kind of statement where I think it is the manager now to move Arsenal forward.
“It’s definitely a turning point, the tactics, he had two days to prepare while Nuno knows this system thoroughly, and Arsenal were magnificent in the way he handled it today. “
“Everyone worked hard, they are not too compact. It’s not easy to play with a new system, but everyone knew their roles and responsibilities.
“They were recovering bodies, Mustafi is gaining confidence and knows its role, they were circulating bodies.
“I really liked the way they worked together as a team, they were always in contact with each other. There was no room at all for the wolves and they could just mop well in the back. It was probably as good as a performance as I saw it. Today, as a group, it was the best performance under Arteta. ”
Arsenal hope the team will maintain performance when it faces another crucial game against Leicester City on Tuesday as it seeks to close the gap in the top four.
