Football Academy Evolution
Free to play. Can manage in England (3 leagues) Italy (2) or Spain (2). This is the second version of the game and is only a few weeks into a season so ideal time to get in there and play.
Fairly simple to get into but dead addictive especially if you end up in a league with a few mates. All transfers are done through emails between managers so you arrange your own signings.
Games are run weekly with Cup games mid-week some weeks. I think Man City are taken (sadly) but plenty of others free and you can move clubs in the game if you want at the end of the season normally so who knows...next Sven? (only better obviously!!)
