Given the trouble that "They call me Revolver" had filling a Fantasy American Football League (which you should find here before its too late) I'm not sure how successful this will be but I have set-up a Fantasy Soccer League.
I've been a member of this site for a few years and its 100% free to play. As someone who knows a medium amount about soccer and very little about the NFL I would say that soccer is a much easier Fantasy game.
You can find the site here: http://fantasy.premierleague.com
And the code for the "Alive & Kicking" league (come on you know you want to join just because of the power of that pun!) is 550105-150777
The season starts in two weeks tomorrow (13 August) so I hope to see you there!
