Perhaps. But when the world was watching, Messi scored a PK in the quarter-final, the semi-final, and the final. If I am coaching a national team, I am studying every game in this tournament and learning exactly what characteristics, what combo of players, what scenarios are most likely to generate PKs and going all-in with that strategy. Maybe Argentina's coach already did.
