“The display was incredible… I’ve never seen anything like it.”

Last week, Watford fans produced one of the most iconic images of the Rainbow Laces campaign – a huge rainbow flag mosaic in the Rookery End at Vicarage Road, as the players took to the field for the Premier League clash at home to Manchester City.

Through global TV coverage of the match, the tifo was seen around the world, helping to send the campaign’s message – that sport and football is “everyone’s game” – to many more communities.

Now, in one of a series of short films produced by the Premier League, the co-founder of the fans’ group that organised the display has explained more about its creation.

Callum Jewell, who was inspired to set up Proud Hornets by seeing other LGBT football supporters groups established across the country, enlisted the help of the club and also The 1881, the movement of core Watford fans that co-ordinates passionate vocal and visible support on the terraces.

The result was a powerful symbol of inclusion, and a moment that Callum says he is unlikely to ever forget.
