The Gunners, who are yet to lose in the top flight this season, welcome their North London rivals to the Emirates Stadium this evening.
Following their 3-0 victory at Aston Villa last weekend, Arteta hopes that Arsenal can continue their positive start to the campaign tonight.
"One of our objectives on Saturday is to maintain the momentum from the win at Aston Villa," the Spaniard told the club's official website.
"It is vital because this is a different game with a different meaning. You can take a lot of positives if you win and there's a lot of negativity when you don't. We'd better be ready, we're at home and we want to win it."
Arteta has made six appearances in all competitions for Arsenal so far this season.
