Arteta says he is ready to help lift spirits around the dressing room to ensure the blip in form does not continue.
"For me, the most important thing is to lead with confidence and remind the players how good they are," Arteta told the club's website.
"When you see some faces with disappointment and doubts, it is not good. They are players of the top level, and after one, two or three performances it is natural - you get doubts, you are not happy with yourself, you get a bit down.
"But we cannot allow that to happen here. It is very demanding to play three or four times in 10 days and bad periods are going to affect the team. So you need everyone on their toes and ready to fight."
