Consequently, after a review, IFAB have clarified the penalty-kick law, stating that such instances will now result in a retake.
"When the penalty-taker accidentally kicks the ball with both feet simultaneously, or when the ball touches the penalty-taker's non-kicking foot or leg immediately after they have taken the kick, if the ball enters the goal, it will be repeated."
This is only one thing to be aware of ahead of next term, as other rule changes were previously announced, following IFAB's annual conference in March.
