Giroud is pleased with his performances and, after scoring a series of braces this season, is now targeting his first hat-trick in an Arsenal shirt.
"We always need the determination," he said. "I think it's a very important thing in football. When you don't have It, you can't play very well, because you need it. It's important for me and all the team. We showed it again tonight.
"[For the first goal] Lukas gave me [the ball] in the right position and I just tried to hit the target and not to shoot too strongly. I liked it. I've tried to work on it in training.
"I liked the second one because I made a good run and Abou gave me a wonderful assist. I did not have a lot of time to finish, and I finished very well.
"I was not so far from the hat-trick again. I want to continue to work hard, to succeed and get my first hat-trick soon."
