My theory is that the cpu affects the human players effectiveness at certain times during a match (moving slower, running slower, turning slower, passing , shooting slower etc). Im ok with this as it does try to simulate the ebbs and flows of real matches.
It forces the human player to dig deeper for solutions (tactics , strategy and the way you play), which I think shows the depth of this game.
I might have to eat my words lads . .I just had two games this morning and they were magnificent matches . .back to the way it played 3 days ago. No charging around nice balanced play .. brill.
