Manchester United youngster Marcus Rashford says his recent hospital visit to see victims of the Manchester terror attack was motivated by a desire to show the city remains united.

Manchester native Rashford, 19, and his United team-mate Jesse Lingard, 24, went to Manchester Children's Hospital on Monday and spent time with children hurt in the May 22 attack, which left 22 dead and 119 injured.

American pop star Ariana Grande, whose show was targeted in the suicide attack, put on a star-studded benefit concert in Manchester on Sunday and Rashford said it was vital for the city to pull together.

"We're with all the families as much as we can be and it's important that the families know that," he told reporters at England's St George's Park training base in Burton-on-Trent.

"That's one of the reasons why we wanted to go and visit the hospitals. We're doing as much as we can to support all the families and the victims of the attack.

"Things like the concert and going to the hospitals, it just shows the families and people around the city that everyone's together and we have to fight it together."
