"Factfiles" are a sub-series of "Bookworms" with a non-fiction angle providing factual information for students on a wide variety of themes. Exercises at the back of each book check students' understanding of the text and provide ideas for activities and project work. Some call it football, some call it soccer, and to others it's "the beautiful game". By any name, it's a sport with some fascinating stories. There is murder in Colombia, and a game that lasts for two days where many players never see the ball. There's the French writer who learnt lessons about life from playing football, and the women players who had to leave the club grounds because "Women's football isn't nice". The cups, the leagues, the World Cup finals, the stars, the rules - they're all a part of the world's favourite sport, the beautiful game.
