Thierry Henry felt Newcastle United did not show enough desire and commitment in Sunday's Tyne-Wear derby with Sunderland.
The Magpies were beaten 1-0 by the Black Cats at the Stadium of Light to make it seven defeats from their last 10 away games.
John Carver's side have dropped to 13th on the Premier League table and former Arsenal star Henry feels it could get even worse if they continue to fail so miserably away from home.
"I have seen them play a lot this year away from home, they have been great at St James' Park but away from home there is no desire, no commitment whatsoever," he told Sky Sports.
"I don't know what it is but as soon as they leave St James' Park they don't perform. You can lose a derby, it hurts, but you have ways of losing and today they were really passive.
"Fans will understand losing but when they play away from home, something is missing."
