From caughtoffside.com:
"Yep, you saw that correctly. This free-kick routine involves a player deliberately falling to the floor and heading the ball whilst on the ground so that his team-mate can then fire in the set piece. Yes we know the exact same result could have occurred if the player just tapped it. Crazy."
That was so dumb it's pulled a "Snake" and ended up on the other side at genius.
Brilliant
Only thing I can see that helping is maybe getting the keeper and defenders a little surprised/off guard. But really its worthless.
