Johan Djourou has called on Arsenal to show more aggression this season in a bid to concede fewer goals and end their trophy drought.
The Gunners have not claimed any silverware since 2005 despite continuing to earn rave reviews for their attractive style of football.
A popular perception is that Arsenal struggle to cope when opposing teams adopt a physical approach, and Djourou accepts this is a matter that must be addressed.
The defender also recognises that the team must tighten up at the back if they are to challenge for the title, after letting in 41 goals last term.
"It is true that 41 goals is too much when you are playing for the top places," Djourou told the club's official website.
"I think sometimes we are missing a bit of aggression.
"It is not that we are not good enough, because the team is good enough.
"We have top players at the back, top players all over the pitch. It is just that we have to be stronger as a unit."
Centre-back Djourou missed almost the entire campaign last season, playing just once against Fulham on the final day.
He has now recovered from the knee injury that kept him out for so long and appears to be vying with new signing Laurent Koscielny for a place alongside Thomas Vermaelen at the heart of the defence.
"Now it is time to step up and start," Djourou declared. "I will always say that, but now I am mature enough.
"We will have to see with the injury because when you have it for so long it is difficult to come straight back into things.
"But I played 90 minutes against Strum Graz and it went well.
"I have to get other games under my belt and hopefully I will be ready."
