A penalty isn't an open net from 3 yards out. Whether it's a sin bin or something, there's no way that the GK should be given the chance to save the pen.
That doesn't make any sense. What if a defender had done the same thing as the last man?
Anyway, as per yesterday's match, it's about a 'goal-scoring opportunity'. Messi had one last night and he hadn't even made it into the penalty area.
Apparently FIFA are actually meeting next month with this on the agenda, so hopefully they'll fix it. Introduce some language around the action taken - ie - if it's just an honest challenge they shouldn't have to go.
