Arteta: Napping Gunners must wake up

MIDFIELDER Mikel Arteta maintains Arsenal must take collective responsibility for their defensive failings against Chelsea.

The Gunners tasted defeat for the first time this season when they went down 2-1 at the Emirates Stadium.

Both goals were preventable, as Fernando Torres outmuscled Laurent Koscielny to hook in Juan Mata's free-kick before the the former Valencia midfielder's second-half delivery was allowed to creep inside the far post after Gervinho had pulled the hosts level just before the break.

Koscielny was kept in the side ahead of 6ft 6ins German Per Mertesacker as captain Thomas Vermaelen returned from illness.

While the France international did not cover himself in glory for either goal, his deflection helping Mata's free-kick past Vito Mannone's dive, Arteta insists every one of the Arsenal players must stand up and be counted.

"We have conceded three goals from three set-pieces in the last two games that cost us points and it is not good enough," Arteta said.

"I don't think it is something to do with the defence. You cannot blame one player, you have to clear the lines so quickly and you cannot allow runners like that in the box, and it was the same sort of ball for both goals."

Arteta, though, insists Arsenal can take confidence from their start to the campaign.

"We have played some of the best teams in the league and we haven't been battered at all. In fact it has been the opposite, we have been better than them through the 90 minutes. I think that is a very positive thing," he said.

Wenger accepts consistency will be the key to Arsenal's chances of mounting a sustained title tilt.

"It is part of human cycle - we are not every day at the same level, and at set-pieces we were poor," he said.

"There was much more in this game for us if we had been more patient and clever."
