Arsenal boss Arsene Wenger is convinced the confidence is returning to his players after their thrashing of Tottenham.
Their victory in the corresponding fixture last term had a galvanising effect, and Wenger believes this result will have a similar impact.
"We have shown quality, spirit and a lot of movement, and that is what we want from our team," he told Arsenal Player.
"The result will help to rebuild belief completely again. There is something special in this team and I am happy that will come out when they play with complete confidence.
"I am confident [it will be a platform]. Let's be consistent. We will gain some belief and confidence from this result, and we will transfer that into our next game and show the same performance."
