Focus and communication can be the keys to a successful season for Arsenal, according to Johan Djourou.

The Swiss international made great strides last term after virtually a year out with injury but the back four of which he was a part came in for criticism as Arsène Wenger's side failed to deliver a trophy despite a promising start to the campaign.

The manager himself identified set-pieces as Arsenal's Achilles heel in 2010/11 and has pledged to put that right in time for the new season. Djourou understands where he and his fellow defenders need to improve.

"I think it's true that we conceded a lot of goals from set-pieces and I think a lot comes down to focus more than anything else," he told

"I have to say as well that in this league players are really going for it. To mark man-for-man is sometimes difficult because there is so much blocking that you need to adapt and we will do that.

"But it's more about focus than anything else, it's more about getting tight to your guy and more communication between the team. Then it will be easier for us.

"Of course it is a team job too. That is something that doesn't always gets mentioned, we should look more into the game and see other ways that you can stop goals.

"But I am sure that as individuals we have looked at ourselves. I am the type of guy who wants to get better. We have meetings after games to talk about where we go wrong and now it's time to learn from it and move forward."
