Lionel Messi has had an excellent World Cup. He's been his team's best attacking player and has coped well with injuries to Sergio Aguero and Angel Di Maria, to go along with Gonzalo Higuain's poor form. Argentina's loss to Germany is not his fault, and he should be remembered as having had a solid World Cup.
But he won't be remembered for that. He'll be remembered for this free kick.
Messi had an opportunity to step up and deliver the goal or assist of his life in the 123rd minute. Instead, he hit the ball a mile high and wide of the near post. He couldn't have hit it much worse, and it'll be the defining image of this World Cup for him.
