FIFA rules broken with penalty rebound

FIFA rules suggest referee Jonathan Moss should have blown his whistle after Harry Kane’s first penalty kick was taken thus denying him his follow up chance on the rebound.

The rules suggest:

When a match is extended at full-time, to allow a Penalty Kick to be taken the extension shall last until the moment that the Penalty Kick has been completed and the game shall terminate immediately the referee has made his decision.

1. After the player taking the Penalty Kick has put the ball into play, no player other than the defending goalkeeper may play or touch the ball before the kick is completed.
2. When a Penalty Kick is being taken in extended time:
   1. The provisions of all of the foregoing paragraphs, except paragraphs (2)(b) and (4)(c) shall apply in the usual way, and
   2. in the circumstances described in paragraphs (2)(b) and (4)(c) the game shall terminate immediately the ball rebounds from the goalkeeper, the cross-bar or the goal-post.
