The initiative by Stonewall and the Premier League aims to promote equality and diversity for all LGBT people in football and beyond.
Old Trafford will don Rainbow Laces corner flags, ball plinths, handshake boards and substitute boards. Our skipper for Wednesday’s match will also wear a rainbow captain’s armband.
During the game, LED boards around the ground will continue to highlight the campaign.
There is extra significance behind this year's campaign, as it will be the first since the formation of United's LGBT+ supporters group, Rainbow Devils. Founded in February this year, group lead Eric Najib provided an insight into how the group was formed.
