Arteta marked his 300th game in charge with a victory secured by Declan Rice and Bukayo Saka.
He later said, "Very proud - it is a big number for this football club. I want to thank everybody, especially my coaching staff who have been with me since day one. Without them, it's impossible, first of all, to do the job and secondly to enjoy it, so I know that I have the best people in the world around me.
"Also the players and the staff that have been with me since day one, supporting, helping me to be a better coach, to learn from them, to inspire me and to enjoy the good moments as well. I wanted to celebrate it with a win, I've got it. Now we have an international break to enjoy it and use the time as well to prepare because what's coming before the next break is going to be really difficult again."
Arteta also stated: "The last two games have been very special. Newcastle, because we had a history there, a lot of scars and a lot of learnings to take, we put that right. Then we had West Ham, losing two games at home in the previous two seasons.
"I told them it was a big opportunity, we’ve had very difficult fixtures since the start of the season, and some very bad injuries as well not helping. Still, the team is performing, playing well, winning today with absolute dominance and without conceding a goal. So, good to get to the international break in this spirit."
