I have never seen my right-footed freekick specialist scoring a curve ball from a direct free kick from the right side of the field. These free kicks are typically taken with the left foot. So if the player is not left footed, he will not score like that. This is the only part of the game where the preferable foot matters imo. Since I discovered this, I only train free kick ability for a player who is both left and right footed.

Has anyone seen the same while watching the games? Or the opposite?
