Arsene Wenger's side let a three-goal lead slip at home, to Anderlecht in the Champions League, and also lost 2-1 at Swansea City in the Premier League.
After relinquishing a winning position, twice in five days, Arsenal players must banish self-doubt if they are to restore good times at the Emirates Stadium, captain Mikel Arteta said on Monday.
Before the international break, Arsene Wenger's side let a three-goal lead slip at home, to Anderlecht in the Champions League, before leading and losing 2-1 at Swansea City in the Premier League.
Spaniard 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 Arsenal 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."
Arsenal are sixth in the league table with 17 points from their opening 11 games, 12 adrift of leaders Chelsea, and second in Champions League Group D, looking likely to qualify for the last 16 with two fixtures remaining.
Arteta says his team mates must keep their focus on their long-term goals instead of dwelling on a poor start to November.
"We have two games, against Manchester United and (Group D leaders) Borussia Dortmund, at home, and if we get the crowd with us from the start, and get the results then it will be a very different story again," he said.
"A week ago, after three wins in a row, the place was getting back to normal with everyone looking happy. Then after two disappointing results, (it is down).
"It is a rollercoaster at the moment but we need to manage the emotion because this is a long-term situation and we need to be where we want to be in April and May, so let's be patient," concluded Arteta.
