I donīt know if there is a difference in ball physics, a couple of days ago saw a video of E3 i believe, and 3 things from past Fifaá all happened:
the ball hitting the post a lot.
the ball hitting the post and coming back straight to the attackers feet to score.
the ball hitting the bar and then the back of the keeper
If the ball physics were really different, these 3 things probably would stop happening so frequently...
