Neville hit out at the Arsenal defence at half time, labelling it "naive" in the way it stood up to the Foxes' attacking display.
"I have to say, their new centre-back, it's so irresponsible what he does," says Neville, speaking on Sky Sports.
"He is there at that back post, he drifts forward, I have no idea what he is doing.
"He drifts forward and leaves a massive void for the rest of his team to cover, and they can't cover it. It's poor from him."
