If there is a deflection by the goalkeeper over the goal line during a penalty kick, what is the restart?

When a goalkeeper deflects the ball over the goal line during a penalty kick, the appropriate restart is a corner kick for the attacking team. This is because the ball is considered to be in play until it completely crosses the goal line. If the goalkeeper touches the ball and then it goes over the goal line, the touch by the goalkeeper does not prevent a goal from being scored; instead, it results in the ball being out of play. Therefore, the attacking team is awarded a corner kick since the last touch by the defending player (the goalkeeper) caused the ball to cross the goal line without resulting in a goal.

The other options do not apply in this scenario. A goal kick would be awarded if the attacking team last touched the ball before it went out, which is not the case here. An indirect free kick is awarded for specific fouls or infractions, not for this situation. A drop ball is used to restart play when the game is interrupted for reasons not covered by the rules but does not apply when the ball goes out of play due to a play that ended with the goalkeeper touching the ball.
