Argentina is confronting a once-unimaginable reality: a national team without soccer great Lionel Messi.

On Tuesday, 39-year-old Messi bid farewell to international soccer after 21 years, 126 goals, two Copa América titles and a World Cup championship, scoring a penalty and setting up Argentina's other two goals for a 3-0 victory over Benin.
