Patrice Evra accused Luke Shaw of 'laziness' in the build-up to Crystal Palace's opening goal against Manchester United.
Ole Gunnar Solskjaer's side found themselves 1-0 down at half-time following Andros Townsend's seventh-minute strike.
It came after a strong start from the visitors, who caught United cold on the counter-attack in the early stages.
Jeffrey Schlupp burst down the United right and sent a cross to the back post where Townsend was left unmarked to fire past De Gea.
On the replay, Shaw was highlighted by Evra after he was pictured jogging back into position, with his man, Townsend, eventually scoring the goal.
After a period out injured, Evra believes Shaw must adapt his game as he may have lost a yard of pace.
"I think it's laziness, he's guessing and that's the worst," Evra said at half-time. "I've made those mistakes where someone is crossing the ball and I'm not running. You have to be in line with your centre-backs and then you have to sprint to be on the same line as Lindelof.
"You can see he's guessing. I call it laziness. Maybe Luke Shaw has been injured and he doesn't have the same speed because when I was guessing it's because I was trusting my speed.
"Maybe now he has to adapt his game because he's not as fast as he used to be. He can't guess anymore."
