Now listen carefully. To perform a Rabona you must first know if your player can do it. A player must have these stats to perform it:
Weak foot frequency 3 or lower.
You can edit someones stats or use these players:
Lionel Messi, Adriano, and Cristiano Ronaldo among others.
Now you must know what foot the player uses. This is crucial. You should try a few practice shots first.
Here it goes. Run(not sprint) parallel to the penalty areas' front line. Run from left to right if your player is left footed and the opposite for right footed. Then press shoot(square) and the direction of the goal. It should then be a Rabona. Sometimes it's not so obvious if you've done it or not so check the replay. It takes practice to actually score a goal with it but it's a neat trick.
If this was helpful drop a comment. I'll add a video later.
