Emery said, "Our performance over the 90 minutes was very important; to be together and with our performance we found each moment and each player.
"It was an important goal for Aaron [Ramsey] and an important goal for us. The best performer for us is every player."
On Arsenal finding themselves in the top four, he added: "I believe in us, we believe in our process but also we must keep taking confidence. I think we are in the first competition in the war. It is very difficult but we must prepare, continue improving and show big commitment."
