The 12th Man

Yahoo Sport travelled to Reykjavik to tell the story of the Tólfan (The 12th Man); Iceland's viking football fans are famous for their Thunderclap chant. Competing at Euro 2016 was a huge moment for the Icelandic national team and the fans who drove them to success. Now that Iceland have qualified for their first ever World Cup, the world better prepare for even an even louder, more passionate Tólfan display.
