The Gunners have won their last two Premier League games, including a 4-1 success over Reading last weekend.
Arteta thinks that a three-day period of rest and recovery during the international break has worked wonders for a rejuvenated squad.
He told the club's official website: "We had three days free to get some time with the family and relax our minds from football. I think sometimes that's very good.
"[After the break] we trained really hard in the last week and this week as well. And I think we played very well [against Reading]. We had a really high tempo right from the start. I think we had a lot of good combinations around the box. We were in control and we played some really good football.
"We're on a very good run in the Premier League but we have to keep going. We know that we're depending on other results, so let's see what happens."
