The Gunners walked away with all three points at Selhurst Park thanks to a first-half Gabriel Martinelli header and a late Marc Guehi own goal.
dominated the opening exchanges but the Eagles challenged Arteta’s side after the restart as the visitors failed to create second-half chances in Gabriel Jesus’ competitive debut.
“We need to be more ruthless in front of goal,” Arteta said.
“We had a situation to finish them better, even in the second half, but that’s something that has to come. We haven’t scored a lot of goals, we lacked that real edge.”
Still, the Gunners boss was pleased with his squad’s overall effort, a marked improvement over their 2-0 loss to Brentford at the start of last season.
Martinelli nearly put Arsenal on the scoresheet early in the first half when the ball landed at his feet the edge of the six-yard box, but the Brazilian’s effort sailed well wide across the face of goal.
