from the main menu (the one with the stadium scrolling in the background), select the second big esagon by hovering your mouse on it, there should appear a single smaller hexagon below it, click there and you'll be redirected to your formation

on the right to your formation, there's four buttons: the top left one lets the game choose the best players for you, the top right one "clones" your team into one of the extra slots (you have to do this if you want to choose between more than one formation or lineup before a match starts, as you can't change it when you connect to an opponent or play against the cpu). The one on the bottom left, I have no idea, and the one on the bottom right deletes a formation, if you have 2 or more.

You can change your captain and who shoots pks, free kicks and throw ins by pressing the third button on the upper left corner, above your players' list. Your captain determines which shirt your team will be wearing.
