Go into edit mode and edit one of the blank teams such as Team A so that all their players are the smallest they can be.
Then start an exhibiton with England (or anyone with a decent free-kick taker ) and play against the edited Team. Make it so no subs can be made and set the difficulty to beginner.
Now once you have possession you will need to run the ball towards the edge of your opponants area then turn back so you have your back to goal and then stop and hold RB, this will cause your player to put their foot on the ball and fend off the challenge from behind. Back into the player trying to tackle you and they will give away a free-kick.
Choose Beckham to take the free kick then just simply lift it over the tiny wall and into the side of the goal where the keeper isn't stood.
It might take a couple of practice free-kicks before you start scoring but you will start to bang em in eventually. Its best to hold back on the analogue stick if you are close in.
Took me 2 10 min matches to gain this achievement.
