Dont expect to get a satisfiying explanation.

You have NO INFLUENCE WHATSOEVER to the outcome of a match. The only thing you can do is setup formation, tactics and train skills etc. That doesnt really mean it wins or looses a game for you. I see every game as 50:50 because i had so many bad beats against really bad teams (statwise) and i gave up spending too much time..its just not worth it. You have no ability to minimize the bad outcomes. I lost games against bot-teams with 2 injured players on the field. In fact this game makes no sense to me. The worst about it is you dont get any help from the designers. ITs a money making machine and thats it. They dont care if your happy.
