Maguire was subjected to criticism following his showing for England against Germany in their Nations League clash on Monday.
Despite losing his spot at club level, Gareth Southgate stuck by the defender and started him at Wembley Stadium.
But he failed to deliver an assured performance at the back as he was at fault for two Germany goals in the thrilling 3-3 draw.
Maguire faced more criticism, with Carragher calling it 'justified'. He also believes the 29-year-old can't save his Man United career, calling for a move away to start afresh.
The Liverpool legend wrote in his Daily Telegraph Column: "My question to Maguire is this: 'Do you still have that same fury in you?'
"Too often, it looks as if the weight of the world is on his shoulders, like he is a startled bunny more than the authoritative centre-back he was.
"I think it is too late at club level. I wrote last year he was fighting for his Manchester United career.
"He needs this to be his final season at Old Trafford and start afresh.
"Now it is England's problem. When I watched Maguire in the last two games, I felt sorry for him. But that is not a good look for any sports person.
"Sympathy will not get him back where he was two years ago."
Maguire's outing against Germany poses the question over whether he should start at the World Cup later this year.
And Carragher reckons Southgate must assess if the under-fire player is mentally right to perform for England in Qatar.
"Criticism of his performance against Germany is valid and justified and Southgate must assess if Maguire is mentally right for a World Cup, able to show he can put all the issues behind him," he added.
"In the past, it is something Maguire has struggled with. How can the manager make such a big call before the opening game against Iran unless Maguire is playing for his club?"
