Fulham boss Scott Parker accused his players of not being "streetwise enough" as their relegation fears intensified after defeat at Aston Villa.
The Cottagers were on course to leapfrog Newcastle into 17th spot when Aleksandar Mitrovic pounced on an error by Tyrone Mings to fire the visitors ahead at Villa Park.
However, substitute Trezeguet scored twice as Villa hit three in the final 12 minutes to leave Fulham three points from a position of safety.
"At certain moments in the game, you have to understand where you are and what you need and we didn't manage that," said Parker.
