Harry Maguire said the Manchester United players will rally around David de Gea after his mistake gave Watford the lead at Vicarage Road on Sunday.
United fell to their seventh league defeat of the season in a disappointing performance against the team who sit bottom of the league and it was a howler from the Spaniard that gave them the lead.
De Gea was beaten at his near post by Ismaila Saar in the 50th minute and he had his face in the turf as he despaired at his mistake. But Maguire, who spoke after the 2-0 defeat, has backed the United goalkeeper to bounce back.
"David is a top keeper. I have only been here a few months but he is a world class keeper. We will get round him and on Boxing Day I am sure he will pull off a top save," he told Sky Sports.
The sentiment was also backed by Ole Gunnar Solskjaer who was not critical of his shot stopper.
"It's one of those things," he told Match of the Day. "He's been so good in training and focused. One goal is a mistake and the second is penalty. David's been very confident lately and I don't look at any other way."
