Arsenal boss Unai Emery hailed matchwinner David Luiz for victory over Bournemouth.
Luiz struck the only goal of a tense encounter.
Emery said, "The most important thing is to have a lot of corners offensively. In this match, we had a lot of corners in the first half, but in the second half we had less. When we are taking that corner, we can score. We did that today and It's important for us to have confidence with different players scoring.
"He's very positive. Every time he's speaking about positive things and helping young players. He came late into the squad but really, his commitment is very high with us, and his behaviour is too. Everybody is happy with that."
