Take control of a team, work your way up the leagues, and become the best manager in the game.. more realistically, try and become the second best manager in the game; the guy in charge of Bath is quite awesome.
The Football Club Manager is currently a public beta release, it has a maximum of 256 users and some functionality may be a little on the dodgy side. But, big plus, it's entirely free, at the moment you couldn't pay even if you wanted to. Which you won't..
The game has most of the features you'd expect from a football management game, most of which work, take a look at the screenshots below, then sign up!! You'll need a valid e-mail address, and to think of a cool manager name.
