Defender Calum Chambers is confident Arsenal can use the morale-boosting 2-1 Capital One Cup victory over North London rivals Tottenham to kickstart their season.
A brace from midfielder Mathieu Flamini, including a superb 25-yard volley late in the second half, at White Hart Lane proved enough to seal a place in the fourth-round draw, which will see the Gunners head to Sheffield Wednesday.
Chambers believes the performance of Arsene Wenger's team, which saw several changes from the Premier League defeat at Chelsea, shows the players have the character needed for the challenges ahead, with a trip to Leicester at the weekend swiftly followed by a home Champions League tie with Olympiakos.
"You want to get good results and build up momentum so hopefully we can take what we learnt into the next game,'' said Chambers, who had deflected in an own goal for Spurs' equaliser.
"We were resilient and in the times where we were under a lot of pressure I thought we were compact. Together as a team we knew our jobs and we defended well.
"We were 1-0 up and then they came back to 1-1 so I think we showed a lot of character to keep our faith, keep our composure, keep playing and get the result by getting a goal to get the win.''
Meanwhile, Arsenal have said they will work with both the authorities and Tottenham Hotspur to investigate an incident in which some of the club's travelling support ripped down hoardings at White Hart Lane.
