I did this with the help of another player but you can make it as well alone with a second controller..
You need to use a throw in looking to the penalty center. Throw the ball (hold "a" just a couple of secs) and wait for the first rebound, then head your player to the ball and inmediately hit dpad+a towards goal.
Note 1. Dont hit straight so the goalkeeper probably will save the goal.
Note 2. Use a very good team like Brazil against a very bad team like Solomon Islands (Oceania) to enhance your chances.
Note 3. Works on both sides of the field.
You need some practice first (so you are familiar with player's movements). Below there is my clip getting the chievo..
