The riff at the heart of this chant comes from the White Stripes song Seven Nation Army, which became one of football's most recognisable terrace anthems after fans around the world adopted its simple, pounding melody. Supporters have long swapped in the name of a favourite player, and Erling Haaland's version spread through stadium singing and short social media clips as his goals made him one of the sport's biggest stars. It remains popular because the chant is easy to join, instantly understood by football fans, and perfectly timed to a celebration.
