There is nothing else in football like a World Cup penalty shootout. It's the ultimate all-or-nothing showdown betwixt outfielder and goalkeeper. Score or don't. In or out. Winner stays on.
The penalty shootout is a test of technique, mentality and preparation. It might not be a perfect tie-breaker but it's the fairest we have and its drama is unmatched. Teams that go beyond the group stage at the World Cup had better be ready even if they never truly can.
