Rory is obsessed with football! Everything he owns is emblazoned with the logo of Arden United - even his underpants. Trouble is, he doesn't always play by the rules, and week after week, gets sent off with a dreaded 'red card'. If he's not careful, he'll be dropped from the team for ever. One day, he buys a fantastic Arden United duvet cover. But this is no ordinary duvet. Rory is promised that if he sleeps beneath it, he'll magically become Arden United's star player. The reality is even more exciting than that, because when he leaps on to the pitch, he finds that the teams who are playing are aliens, with four arms and four legs each - and he's one hundred years in the future! Rory has his work cut out for him keeping up with his fellow team-mates, but in the course of this memorable match, he learns a lesson which will stand him in good stead for the future!
