Former Liverpool centre-back Jamie Carragher has claimed that Arsenal's defenders 'do not know what they are doing' as the Gunners suffered another disappointing result at the weekend.

Freddie Ljungberg picked up his first victory as interim boss away to West Ham United on Monday night, but the capital side lost 3-0 to Manchester City at the Emirates Stadium on Sunday afternoon.

Carragher has said that the performance of the team's defence is part of a "disease" that has become engrained at the club in recent years.

"Every time I watch them play, every time the ball comes in on the attack they just drop off," Carragher told Sky Sports News. "Remember the Norwich goal where [Shkodran] Mustafi and [David] Luiz let [Teemu] Pukki get it and turn?

"It's something that needs to change on the training ground. Keep the line and press. I said on commentary about it. They drop off when they should press, they press when they should drop off. It's like they don't know what they're doing.

"Sometimes you look at a big mistake in a goal; Calum Chambers loses the ball second half, Arsenal go through on goal. Everyone can see that. But these are things that kill the team. It's your job and sometimes you think you're looking after yourself, but you're hurting the rest of the team. That's why David Luiz isn't playing.

"I'm glad he's gone with Calum Chambers. We know Luiz isn't good enough, that's all he does, drops off to protect himself. But he's catching the disease as well too - make the mistakes being aggressive and going forward, I'm sure that's what Freddie Ljungberg wants. Do it that way, doing the right thing."

Arsenal, who have only kept two clean sheets in the Premier League this season, will be looking to return to winning ways when they travel to Everton next weekend.
