Goals either side of half time from Bukayo Saka and Alexandre Lacazette gave the Gunners a crucial win in their quest for European football next season.
Arteta was appointed as manager of Arsenal back in December but has had a mixed few months in his first managerial role.
However, the win over Wolves was Arsenal’s fourth in a row in all competitions.
And speaking on Match of the Day, Keown can only see good signs for the future.
“They’re looking so much more resolute,” he said.
“I’m immensely impressed with Arteta, I think that’s the first sort of statement where I think that this is the manager now to take Arsenal forward.
“It’s definitely a turning point, the tactics, he had two days to prepare whereas Nuno knows this system inside out, and Arsenal were magnificent in the way they dealt with that today.
“Everyone was working hard, they’re not too compact. It’s not easy to pick up playing a new system but everyone knew their roles and their responsibilities.
“They were getting bodies back, Mustafi is growing in confidence and knows his role, they were getting bodies around.
“I really liked the way they worked together as a team, they were always in contact with each other. There was no space at all for Wolves and they could just mop up nicely at the back. This was probably as good as a performance as I’ve seen. As a group today, that was the best performance under Arteta.”
Arsenal will be hoping that the team keep up the performance level when they face another crucial game against Leicester City on Tuesday as they look to close the gap on the top four.
