The Switzerland international echoes boss Arsene Wenger, who last week bemoaned his side's set-piece frailties, but also puts emphasis on teamwork to remedy problems at the backJohan Djourou says Arsenal must improve their teamwork and focus if they are to succeed in defence this season.
The Swiss central defender agrees with his manager Arsene Wenger that defending set-pieces was a weakness for the Gunners last term, but says that there is mental work to be done as well.
Djourou told the club’s official website: “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.
“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.”
And the 24-year-old believes Arsenal must look at themselves, both as individuals and as a group, to turn their fortunes around after their collapse in form last season.
“Of course it is a team job too,” said Djourou.
“That is something that doesn't always get 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.”
Reports continue to link Arsenal with at least one new central defender in the transfer market to help solve their recurring problems at the back.
