Fake Shot Runs Over the Ball
FIFA 21 free kicks provide players with the option of performing a fake shot dummy over the ball. This requires you to select a second and/or third man free-kick. To call the second man press LT/L2, and for the third man, press RB/R1. To perform a dummy, you just need to do a fake shot whilst holding the respective button of the player. You can also shoot with the second and third man, LT/L2 + B (the second man), and RB/R1 + B (third man). Make sure you aim to compensate for the curve when doing this.
Sometimes you need to pass/lay off to switch it up, this can also catch your opponent off guard. Here are the controls for this – LT/L2 + A (second man) and RB/R1 + X (third man). This can provide a different angle of approach, which will often give you an open shot on goal if not defending properly.
