What happened: Lionel Messi had his first-half penalty kick saved by Egyptian goalkeeper Mostafa Shobeir during their World Cup Round of 16 matchup. The attempt was struck low and to the right before being punched away. Argentina trailed 1-0 at the time of the miss.

Why it matters: The sequence squandered a critical opportunity to equalize in a high-stakes knockout game. A successful conversion would have shifted the momentum and added to the captain's historic scoring tally. Advancing to the quarterfinals now requires overcoming a deficit without the benefit of that spot-kick.

What to watch: Argentina must find another way to break down the Egyptian defense to avoid elimination. The remainder of the match will dictate whether this sequence defines their tournament exit.
