Johan Djourou has warned the rest of the Barclays Premier League to expect a more aggressive Arsenal next season.
The Gunners, currently away on a training camp in Austria, failed to stay the distance in the last title race as lapses in concentration at the back proved costly. Arsenal leaked 41 goals - nine more than champions Chelsea and some 13 extra than Manchester United, who had the meanest rearguard in the top flight.
"It is true that 41 goals is too much when you are playing for the top places," the defender told www.arsenal.com.
"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.
The 23-year-old, though, is ready for the challenges ahead as he looks to battle summer-signing Laurent Koscielny alongside Thomas Vermaelen at the heart of the Gunners 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 Sturm Graz and it went well. I have to get other games under my belt and hopefully I will be ready."
