Emery pleased as Arsenal defeat Bournemouth
David Luiz was the matchwinner as Arsenal edged past Bournemouth at Emirates Stadium to move up to third in the Premier League.
Luiz glanced home Nicolas Pepe's ninth-minute corner for his first goal since his summer arrival from Chelsea.
Bournemouth improved after the break and went close through Callum Wilson, but they rarely troubled Bernd Leno in the Arsenal goal.
The Gunners move above Leicester, Burnley and Crystal Palace with the win, while Bournemouth stay 10th.
Arsenal boss Unai Emery said, "We were speaking before the match, the first four matches we played, today we wanted to do one step ahead, doing better and controlling better the match but knowing it was going to be difficult.
"We played with a very good organisation, defensively very strong. We scored one goal and got into their box with possibilities to score goals.
"The second half was a very good opportunity to keep our confidence, to get better with the ball and stop their action with the ball. We did it perfectly in the first half but in the second half, maybe because the chances arrived late, we lost that.
"We are very happy with that result and very proud of that result."
