This is probably how it is in this game; the players don't have artificial intelligence. After having watched many matches, I have the impression that everything is 'constructed' (made to happen). For example, a player may appear to deliberately give the ball away to the opponent so that the opposing team can score a goal or change the statistics so that it follows the calculated statistics and score by the program. Hence, I suspect that for a particular match, many things (but not all) may already have been decided before the match started or before each half of the match.
