Our Alfie Allen has been featured in numerous movies and TV series, but is probably best known for his role as Theon Greyjoy in the global hit series Game of Thrones.

In this two-part series, we follow Alfie's geographical, cultural and historical journey across the United Kingdom in search of football's roots and discover how the game evolved through a broad range of themes including the fans, stadiums, FA, leagues, gender, diversity and chants. Allen is granted exclusive access to several stadiums and interviews with footballing icons.

This is something of a passion project for Allen, who has been a huge fan of the sport since childhood. In his younger years, he played regularly for the youth camp of his favourite team, Arsenal FC, a London-based Premier League club. Here he is talks about the club and what it means to him. The show explores the stories, moments and characters that have defined football over the past century.
