Today Sega released the demo for Football Manager 2010 in two flavors vanilla and strawberry. The vanilla demo features the English and Scottish leagues, with no player photos or logos, so as to reduce the size of the download. The strawberry demo, which I recommend if you're a footballer like me, includes all player pictures and logos, with quickstarts for some of the world leagues.
Although the demo size is just above 1 GB, it will be worth all the features included. You can find Football Manger 2010 vanilla and strawberry demos and many other games at the GameSpot Downloads Page.
