I'm not sure about controlling an entire team at once in real time(if that is what you are referring to) I don't think even fifa does that....
But you should definitely be able to create a soccer game where, like in fifa, the players have some basic AI and once you select a player that behavior is paused and control is given to you untill you deselect the guy at which point his AI resumes.
Of course one assumes you could make the AI as complex/good as you want, I used the word basic because with my current skill level that's how the ai would turn out if I attempted something like that, basic, super, super basic...
As to whether or not there are already soccer(or other sports) games created with C2, I don't know, you should probably ask google.
