Carragher: Arsenal's defenders don't know what they're doing in City debacle

Arsenal defenders looked clueless in their defeat to Manchester City with their performance part of a "disease", Jamie Carragher told Sky Sports.

The Gunners shipped three first-half goals at the Emirates as Manchester City ran riot despite registering only four shots on target, as the hosts were picked apart with ease.

Arsenal have conceded only five goals fewer than bottom-of-the-table Watford and kept two clean sheets all season - the joint-fewest in the Premier League, with Carragher incredulous about the manner of their latest showing.

"Every time I watch them play, every time the ball comes in on the attack they just drop off," he said. "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."
