Sir Alex Ferguson and Sven-Goran Eriksson will both lay wreaths on the pitch before Sunday's Manchester derby in honour of those who died at Munich.
The two managers will lead the teams out of the tunnel prior to kick-off at 13:30 GMT. Both sides, who will be wearing special retro kits for the game, will be accompanied by 23 mascots wearing shirts with the names of the air crash victims on the back.
Sir Alex and Sven will place the floral tributes on the centre spot, before joining the whole stadium in a minute's silence.
Fans are urged to be in the ground by 13:20 GMT. Supporters will not be admitted to the seating area after that time until the pre-match tribute has been completed.
