Ten Hag was asked today whether he has to be protective of Maguire given how much negative attention he has been attracting lately.
"I have to back him. But I back him because I believe in him," said the Dutchman.
"You see his career, almost 50 caps for England. For Leicester and Manchester United he's performing really well.
"What you see is he has a high potential. Then it is about him.
"The players in the dressing room, the coaches, the manager, we all believe in him. That's what I told him. I'm sure he can do it. He will turn around this. I am really convinced of that."
