LONDON • Manchester United are willing to play supporting act to a star-studded concert on Sunday headlined by Ariana Grande.

A tribute game in Manchester for midfielder Michael Carrick has been rescheduled from 4pm to 2.30pm to avoid congestion at a train station, so that concert fans would not be arriving at the same time that football fans are trying to leave, reported Billboard.

American pop star Grande had announced on Tuesday that she would return to Manchester to anchor a concert for the 22 victims of the deadly attack on her show last week, reported Agence France- Presse.

Justin Bieber, Coldplay, Katy Perry, Miley Cyrus, Pharrell Williams, Usher and Take That will lend their voices for peace and sanity at the One Love Manchester concert.

"Our response to this violence must be to come closer together, to help each other, to love more, to sing louder and to live more kindly and generously than we did before," Grande, 23, said.

She had said that she was "broken" and had suspended her world tour after the bomb went off at the Manchester Arena at the finale of her show on May 22.

Fans who attended that show will be offered free tickets to Sunday's event at the Old Trafford cricket ground, with the rest sold to raise money for the affected families.

"Music is meant to heal us, to bring us together, to make us happy. So that is what it will continue to do for us," Grande said.

The show will be aired live on BBC TV, BBC Radio and Capital Radio networks. It will also be streamed.
