Despite securing three points and a clean sheet at Newcastle, Emery wants his side to perform better when they host Burnley.
Arsenal manager Unai Emery wants his players to improve their performance despite seeing them start the new Premier League campaign with a win at Newcastle last weekend.
Pierre-Emerick Aubameyang scored the only goal in the clash against the Magpies at St James' Park to hand the Gunners a narrow win last Sunday.
Speaking ahead of their next match against Burnley at the Emirates this Saturday, Emery stressed that their build-up play must get better.
"We need to improve. We were happy with the three points and we played seriously, but I want to improve on each position for us," Emery said at Thursday's news conference.
"We need to and can improve with the same players and other players who were out of that match. My idea is to be more competitive in each position.
"We worked very well that match, above all defensively we worked very compact. The balance, we must improve."
He added: "The build-up needs to be better. We need better progress with our combinations and need to be safer each moment when we pass the ball between us.
"When we progress with the ball like a team we can find better positions and solutions in the attacking third.
"The clean sheet is important but the most important thing is to win. If we can win scoring a lot of goals, good. If we can have a clean sheet each match, it’s perfect."
